What are the greatest common factors of 63 and 49?
The factors of 63 are 7*3*3 (or 7^1 * 3^2) The factors of 49 are 7*7 (or 7^2) When finding the GCF, you can use the highest power of a common factor. Is this case, the highest common factor is (7^1) since 63 only has a 7^1 The answer is 7.
What is the LCM of 3 4 5 6 7?
Write down the factors of each number. Hence 3 = 1,3 4 = 1,2,2,4 5 = 1, 5, 6 = 1,2,3,6 7 = 1, 7 Hence 1, is common to all number. 2, is common to two numbers 3, is common to two numbers 5 is common to one number 7 is common to one number. Hence 1 x 2 x 3 x 5 x 7 = 210 the LCM.
What is the gcf of 7 8 3?
The Greatest Common Factor (GCF) for 3, 7, 8 is 1 3 = 1, 3 7 = 1, 7 8 = 1, 2, 4, 8
What is 1 over 7 plus 2 over 3 in simplest form?
1/7 + 2/3 (the common denominator is 21)= (1 x 3)/(7 x 3) + (2 x 7)/(3 x 7)= 3/21 + 14/21= (3 + 14)/21= 17/21, which is in its simplest form since both the numerator and the denominator do not have other common factors than 1.

What is the greatest common factor of 144 and 175?
The greatest common factor of 144 and 175 is 1. Factoring completely, we determine: 144 = 12 * 12 = 3 * 3 * 4 * 4 = 3 * 3 * 2 * 2 * 2 * 2 * 1 175 = 7 * 25 = 7 * 5 * 5 * 1 Since the only factor these have in common is 1, 1 is their greatest common factor.
