Given numbers are 291, 557, 820, 111
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 557) = 162087
GCD(291, 557) = ( 291 x 557 ) / 162087
= 291 / 557
= 291
Step2:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
Step3:
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
= 1 / 111
= 1
So, Greatest Common Divisor of 291, 557, 820, 111 is 1
