Steps to Calculate GCD of 122, 542, 778, 805 using LCM Formula
Given numbers are 122, 542, 778, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(122, 542) = 33062
GCD(122, 542) = ( 122 x 542 ) / 33062
= 122 / 542
= 122
Step2:
LCM(2, 778) = 778
GCD(2, 778) = ( 2 x 778 ) / 778
= 2 / 778
= 2
Step3:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
So, Greatest Common Divisor of 122, 542, 778, 805 is 1
