GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 787) = 332901
GCD(423, 787) = ( 423 x 787 ) / 332901
= 423 / 787
= 423
Step2:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
Step3:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
So, Greatest Common Divisor of 423, 787, 893, 125 is 1
