Given numbers are 291, 432, 605, 372
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 432) = 41904
GCD(291, 432) = ( 291 x 432 ) / 41904
= 291 / 432
= 291
Step2:
LCM(3, 605) = 1815
GCD(3, 605) = ( 3 x 605 ) / 1815
= 3 / 605
= 3
Step3:
LCM(1, 372) = 372
GCD(1, 372) = ( 1 x 372 ) / 372
= 1 / 372
= 1
So, Greatest Common Divisor of 291, 432, 605, 372 is 1
