A factor is a divisor - a number that will evenly divide into another number.
One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
The factors of 462 are 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, and 462.
The factors of 2940 are 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 49, 60, 70, 84, 98, 105, 140, 147, 196, 210, 245, 294, 420, 490, 588, 735, 980, 1470, and 2940.
The common factors are 1, 2, 3, 6, 7, 14, 21, and 42.
This would mean that the greatest common factor is 42.
The greatest common factor of 2940 and 3150 is 210. Source: http://www.mathwarehouse.com/arithmetic/numbers/GCF/greatest-common-factor-calculator.php
The least common multiple of 462 , 147 = 3,234
The number 462 has prime factors as 2,3, 7 and 11. Their product is 462.
420
210, 330, 390, 420 and 462
The GCF is 42.
The only common factor of 41 and 462 is 1.
2940 is an even number and all even numbers are divisible by 2. It is also divisible by 1, by 2940, and by all of its other factors.
The best way to do this is to factor both numbers. 2940 = 2 * 2 * 3 * 5 * 7 * 7 3150 = 2 * 3 * 5 * 5 * 7 Now take the ones that are common: 2 * 3 * 5 * 7. That's 210 to check, you can take the unused factors. For 2940 that's 2 * 7 = 14 and 14 * 210 = 2940 For 3150 that's 3 * 5 = 15 and 15 * 210 = 3150 The 14 and 15 also tell us we have it right since they share no common factors.
The prime factors of 2,940 are: 2, 3, 5, 7
The lowest common factor is: 1
924
