GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 689) = 291447
GCD(423, 689) = ( 423 x 689 ) / 291447
= 423 / 689
= 423
Step2:
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
= 1 / 947
= 1
Step3:
LCM(1, 373) = 373
GCD(1, 373) = ( 1 x 373 ) / 373
= 1 / 373
= 1
So, Greatest Common Divisor of 423, 689, 947, 373 is 1
