Given numbers are 423, 374, 721, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 374) = 158202
GCD(423, 374) = ( 423 x 374 ) / 158202
= 423 / 374
= 423
Step2:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 423, 374, 721, 291 is 1
