Steps to Calculate GCD of 43, 73, 20, 98 using LCM Formula
Given numbers are 43, 73, 20, 98
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(43, 73) = 3139
GCD(43, 73) = ( 43 x 73 ) / 3139
= 43 / 73
= 43
Step2:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
Step3:
LCM(1, 98) = 98
GCD(1, 98) = ( 1 x 98 ) / 98
= 1 / 98
= 1
So, Greatest Common Divisor of 43, 73, 20, 98 is 1
