Steps to Calculate GCD of 431, 781, 291, 521 using LCM Formula
Given numbers are 431, 781, 291, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(431, 781) = 336611
GCD(431, 781) = ( 431 x 781 ) / 336611
= 431 / 781
= 431
Step2:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 431, 781, 291, 521 is 1
