GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 942) = 176154
GCD(561, 942) = ( 561 x 942 ) / 176154
= 561 / 942
= 561
Step2:
LCM(3, 121) = 363
GCD(3, 121) = ( 3 x 121 ) / 363
= 3 / 121
= 3
Step3:
LCM(1, 924) = 924
GCD(1, 924) = ( 1 x 924 ) / 924
= 1 / 924
= 1
So, Greatest Common Divisor of 561, 942, 121, 924 is 1
