Given numbers are 387, 435, 457, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 435) = 56115
GCD(387, 435) = ( 387 x 435 ) / 56115
= 387 / 435
= 387
Step2:
LCM(3, 457) = 1371
GCD(3, 457) = ( 3 x 457 ) / 1371
= 3 / 457
= 3
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 387, 435, 457, 291 is 1
