Steps to Calculate GCD of 391, 646, 36, 461 using LCM Formula
Given numbers are 391, 646, 36, 461
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 646) = 14858
GCD(391, 646) = ( 391 x 646 ) / 14858
= 391 / 646
= 391
Step2:
LCM(17, 36) = 612
GCD(17, 36) = ( 17 x 36 ) / 612
= 17 / 36
= 17
Step3:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
So, Greatest Common Divisor of 391, 646, 36, 461 is 1
