Steps to Calculate GCD of 49, 56, 69, 54 using LCM Formula
Given numbers are 49, 56, 69, 54
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(49, 56) = 392
GCD(49, 56) = ( 49 x 56 ) / 392
= 49 / 56
= 49
Step2:
LCM(7, 69) = 483
GCD(7, 69) = ( 7 x 69 ) / 483
= 7 / 69
= 7
Step3:
LCM(1, 54) = 54
GCD(1, 54) = ( 1 x 54 ) / 54
= 1 / 54
= 1
So, Greatest Common Divisor of 49, 56, 69, 54 is 1
