Given numbers are 620, 658, 646, 701
The list of prime factors of all numbers are
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 658 are 2 x 7 x 47
Prime factors of 646 are 2 x 17 x 19
Prime factors of 701 are 701
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 620, 658, 646, 701
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 658) = 203980
GCD(620, 658) = ( 620 x 658 ) / 203980
= 620 / 658
= 620
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 701) = 1402
GCD(2, 701) = ( 2 x 701 ) / 1402
= 2 / 701
= 2
So, Greatest Common Divisor of 620, 658, 646, 701 is 1
