GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 953) = 612779
GCD(643, 953) = ( 643 x 953 ) / 612779
= 643 / 953
= 643
Step2:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
Step3:
LCM(1, 277) = 277
GCD(1, 277) = ( 1 x 277 ) / 277
= 1 / 277
= 1
So, Greatest Common Divisor of 643, 953, 756, 277 is 1
