Given numbers are 640, 870, 717, 416

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

Apply this formula for all numbers.

Step1:

LCM(640, 870) = 55680

GCD(640, 870) = ( 640 x 870 ) / 55680

= 640 / 870

= 640

Step2:

LCM(10, 717) = 7170

GCD(10, 717) = ( 10 x 717 ) / 7170

= 10 / 717

= 10

Step3:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

So, Greatest Common Divisor of 640, 870, 717, 416 is 1
