Factors of 15 = 1, 3, 5, 15 Factors of 28 = 1, 2, 4, 7, 14, 28 Common factors of 15 and 28 = 1 Highest common factor (H.C.F) of 15 and 28 = 1 Two numbers which have only 1 as the common factor are called co-prime. Finding H.C.F. WebGCF of 12 and 15 = 3 What is the Greatest Common Factor? Put simply, the GCF of a set of whole numbers is the largest positive integer (i.e whole number and not a decimal) that divides evenly into all of the numbers in the set. It's also commonly known as: Greatest Common Denominator (GCD) Highest Common Factor (HCF) Greatest Common Divisor …
Find a possible pair of numbers given HCF and a factor of the LCM
WebWe will first find the prime factorization of 12 and 15. After we will calculate the factors of 12 and 15 and find the biggest common factor number . Step-1: Prime Factorization of 12 Prime factors of 12 are 2, 3. Prime factorization of 12 in exponential form is: 12 = 2 2 × 3 1 Step-2: Prime Factorization of 15 Prime factors of 15 are 3, 5. WebThe procedure to find the HCF of number by division method is as follows: First, consider the given numbers and find which is large and small then divide the large number by small number.

WebThe problem is asking for a number (the choices) that have the same factor. So 15's factors are 1 and 5, 15. And then for 8 the factors are 1, 2, 4, 8. So which of the choices is divisible by 1, 2, 4, , 1, 5, 8, 15. 21: is not divisible by 2,5,4 8... While 60 is divisible by all of the factors (1, 2, 4, 5, 8, 15) WebHCF of 12 and 15 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 15 (larger number) by 12 (smaller number). Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (12) by the remainder (3). Step 3: … WebStep 1: Find the prime factors of the given number. Step 2: List the common prime numbers. Step 3: Multiply the common prime number. The result is the HCF of the number. … grimgar of fantasy and ash ch 1
