Steps to Calculate GCD of 542, 490, 81, 188 using LCM Formula
Given numbers are 542, 490, 81, 188
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(542, 490) = 132790
GCD(542, 490) = ( 542 x 490 ) / 132790
= 542 / 490
= 542
Step2:
LCM(2, 81) = 162
GCD(2, 81) = ( 2 x 81 ) / 162
= 2 / 81
= 2
Step3:
LCM(1, 188) = 188
GCD(1, 188) = ( 1 x 188 ) / 188
= 1 / 188
= 1
So, Greatest Common Divisor of 542, 490, 81, 188 is 1
