Steps to Calculate GCD of 781, 772, 170, 481 using LCM Formula
Given numbers are 781, 772, 170, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 772) = 602932
GCD(781, 772) = ( 781 x 772 ) / 602932
= 781 / 772
= 781
Step2:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
Step3:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
So, Greatest Common Divisor of 781, 772, 170, 481 is 1
