Steps to Calculate GCD of 61, 49, 30, 97 using LCM Formula
Given numbers are 61, 49, 30, 97
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(61, 49) = 2989
GCD(61, 49) = ( 61 x 49 ) / 2989
= 61 / 49
= 61
Step2:
LCM(1, 30) = 30
GCD(1, 30) = ( 1 x 30 ) / 30
= 1 / 30
= 1
Step3:
LCM(1, 97) = 97
GCD(1, 97) = ( 1 x 97 ) / 97
= 1 / 97
= 1
So, Greatest Common Divisor of 61, 49, 30, 97 is 1
