GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(444, 416) = 46176
GCD(444, 416) = ( 444 x 416 ) / 46176
= 444 / 416
= 444
Step2:
LCM(4, 640) = 640
GCD(4, 640) = ( 4 x 640 ) / 640
= 4 / 640
= 4
Step3:
LCM(4, 291) = 1164
GCD(4, 291) = ( 4 x 291 ) / 1164
= 4 / 291
= 4
So, Greatest Common Divisor of 444, 416, 640, 291 is 1
