The list of prime factors of all numbers are
Prime factors of 614 are 2 x 307
Prime factors of 424 are 2 x 2 x 2 x 53
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 215 are 5 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 614, 424, 660, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(614, 424) = 130168
GCD(614, 424) = ( 614 x 424 ) / 130168
= 614 / 424
= 614
Step2:
LCM(2, 660) = 660
GCD(2, 660) = ( 2 x 660 ) / 660
= 2 / 660
= 2
Step3:
LCM(2, 215) = 430
GCD(2, 215) = ( 2 x 215 ) / 430
= 2 / 215
= 2
So, Greatest Common Divisor of 614, 424, 660, 215 is 1
