Given numbers are 423, 831, 721, 597
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 831) = 117171
GCD(423, 831) = ( 423 x 831 ) / 117171
= 423 / 831
= 423
Step2:
LCM(3, 721) = 2163
GCD(3, 721) = ( 3 x 721 ) / 2163
= 3 / 721
= 3
Step3:
LCM(1, 597) = 597
GCD(1, 597) = ( 1 x 597 ) / 597
= 1 / 597
= 1
So, Greatest Common Divisor of 423, 831, 721, 597 is 1
