Given numbers are 418, 660, 739, 640

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

Apply this formula for all numbers.

Step1:

LCM(418, 660) = 12540

GCD(418, 660) = ( 418 x 660 ) / 12540

= 418 / 660

= 418

Step2:

LCM(22, 739) = 16258

GCD(22, 739) = ( 22 x 739 ) / 16258

= 22 / 739

= 22

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 418, 660, 739, 640 is 1
