The list of prime factors of all numbers are
Prime factors of 851 are 23 x 37
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 434 are 2 x 7 x 31
Prime factors of 398 are 2 x 199
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 851, 660, 434, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(851, 660) = 561660
GCD(851, 660) = ( 851 x 660 ) / 561660
= 851 / 660
= 851
Step2:
LCM(1, 434) = 434
GCD(1, 434) = ( 1 x 434 ) / 434
= 1 / 434
= 1
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 851, 660, 434, 398 is 1
