Steps to Calculate GCD of 309, 870, 538, 963 using LCM Formula
Given numbers are 309, 870, 538, 963
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 870) = 89610
GCD(309, 870) = ( 309 x 870 ) / 89610
= 309 / 870
= 309
Step2:
LCM(3, 538) = 1614
GCD(3, 538) = ( 3 x 538 ) / 1614
= 3 / 538
= 3
Step3:
LCM(1, 963) = 963
GCD(1, 963) = ( 1 x 963 ) / 963
= 1 / 963
= 1
So, Greatest Common Divisor of 309, 870, 538, 963 is 1
