Given numbers are 216, 656, 640, 387

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

Apply this formula for all numbers.

Step1:

LCM(216, 656) = 17712

GCD(216, 656) = ( 216 x 656 ) / 17712

= 216 / 656

= 216

Step2:

LCM(8, 640) = 640

GCD(8, 640) = ( 8 x 640 ) / 640

= 8 / 640

= 8

Step3:

LCM(8, 387) = 3096

GCD(8, 387) = ( 8 x 387 ) / 3096

= 8 / 387

= 8

So, Greatest Common Divisor of 216, 656, 640, 387 is 1
