Given numbers are 640, 780, 216, 382

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

Apply this formula for all numbers.

Step1:

LCM(640, 780) = 24960

GCD(640, 780) = ( 640 x 780 ) / 24960

= 640 / 780

= 640

Step2:

LCM(20, 216) = 1080

GCD(20, 216) = ( 20 x 216 ) / 1080

= 20 / 216

= 20

Step3:

LCM(4, 382) = 764

GCD(4, 382) = ( 4 x 382 ) / 764

= 4 / 382

= 4

So, Greatest Common Divisor of 640, 780, 216, 382 is 2
