Given numbers are 678, 660, 57, 417

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(678, 660) = 74580

GCD(678, 660) = ( 678 x 660 ) / 74580

= 678 / 660

= 678

Step2:

LCM(6, 57) = 114

GCD(6, 57) = ( 6 x 57 ) / 114

= 6 / 57

= 6

Step3:

LCM(3, 417) = 417

GCD(3, 417) = ( 3 x 417 ) / 417

= 3 / 417

= 3

So, Greatest Common Divisor of 678, 660, 57, 417 is 3
