Given numbers are 640, 158, 737, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 158) = 50560
GCD(640, 158) = ( 640 x 158 ) / 50560
= 640 / 158
= 640
Step2:
LCM(2, 737) = 1474
GCD(2, 737) = ( 2 x 737 ) / 1474
= 2 / 737
= 2
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 640, 158, 737, 140 is 1
