Steps to Calculate GCD of 73, 98, 17, 20 using LCM Formula
Given numbers are 73, 98, 17, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(73, 98) = 7154
GCD(73, 98) = ( 73 x 98 ) / 7154
= 73 / 98
= 73
Step2:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
Step3:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
So, Greatest Common Divisor of 73, 98, 17, 20 is 1
