Steps to Calculate GCD of 781, 913, 206, 122 using LCM Formula
Given numbers are 781, 913, 206, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 913) = 64823
GCD(781, 913) = ( 781 x 913 ) / 64823
= 781 / 913
= 781
Step2:
LCM(11, 206) = 2266
GCD(11, 206) = ( 11 x 206 ) / 2266
= 11 / 206
= 11
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 781, 913, 206, 122 is 1
