The list of prime factors of all numbers are
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 425 are 5 x 5 x 17
Prime factors of 851 are 23 x 37
Prime factors of 248 are 2 x 2 x 2 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 660, 425, 851, 248
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 425) = 56100
GCD(660, 425) = ( 660 x 425 ) / 56100
= 660 / 425
= 660
Step2:
LCM(5, 851) = 4255
GCD(5, 851) = ( 5 x 851 ) / 4255
= 5 / 851
= 5
Step3:
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
= 1 / 248
= 1
So, Greatest Common Divisor of 660, 425, 851, 248 is 1
