Given numbers are 945, 869, 102, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 869) = 821205
GCD(945, 869) = ( 945 x 869 ) / 821205
= 945 / 869
= 945
Step2:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 945, 869, 102, 557 is 1
