Given numbers are 640, 155, 500, 665

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

Apply this formula for all numbers.

Step1:

LCM(640, 155) = 19840

GCD(640, 155) = ( 640 x 155 ) / 19840

= 640 / 155

= 640

Step2:

LCM(5, 500) = 500

GCD(5, 500) = ( 5 x 500 ) / 500

= 5 / 500

= 5

Step3:

LCM(5, 665) = 665

GCD(5, 665) = ( 5 x 665 ) / 665

= 5 / 665

= 5

So, Greatest Common Divisor of 640, 155, 500, 665 is 5
