Steps to Calculate GCD of 781, 578, 309, 112 using LCM Formula
Given numbers are 781, 578, 309, 112
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 578) = 451418
GCD(781, 578) = ( 781 x 578 ) / 451418
= 781 / 578
= 781
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 112) = 112
GCD(1, 112) = ( 1 x 112 ) / 112
= 1 / 112
= 1
So, Greatest Common Divisor of 781, 578, 309, 112 is 1
