Steps to Calculate GCD of 155, 713, 431, 973 using LCM Formula
Given numbers are 155, 713, 431, 973
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 713) = 3565
GCD(155, 713) = ( 155 x 713 ) / 3565
= 155 / 713
= 155
Step2:
LCM(31, 431) = 13361
GCD(31, 431) = ( 31 x 431 ) / 13361
= 31 / 431
= 31
Step3:
LCM(1, 973) = 973
GCD(1, 973) = ( 1 x 973 ) / 973
= 1 / 973
= 1
So, Greatest Common Divisor of 155, 713, 431, 973 is 1
