Given numbers are 420, 651, 567, 316
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 651 are 3 x 7 x 31
Prime factors of 567 are 3 x 3 x 3 x 3 x 7
Prime factors of 316 are 2 x 2 x 79
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 651, 567, 316
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 651) = 13020
GCD(420, 651) = ( 420 x 651 ) / 13020
= 420 / 651
= 420
Step2:
LCM(21, 567) = 567
GCD(21, 567) = ( 21 x 567 ) / 567
= 21 / 567
= 21
Step3:
LCM(21, 316) = 6636
GCD(21, 316) = ( 21 x 316 ) / 6636
= 21 / 316
= 21
So, Greatest Common Divisor of 420, 651, 567, 316 is 1
