Given numbers are 640, 569, 630, 488
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 569) = 364160
GCD(640, 569) = ( 640 x 569 ) / 364160
= 640 / 569
= 640
Step2:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
Step3:
LCM(1, 488) = 488
GCD(1, 488) = ( 1 x 488 ) / 488
= 1 / 488
= 1
So, Greatest Common Divisor of 640, 569, 630, 488 is 1
