Steps to Calculate GCD of 73, 45, 70, 19 using LCM Formula
Given numbers are 73, 45, 70, 19
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(73, 45) = 3285
GCD(73, 45) = ( 73 x 45 ) / 3285
= 73 / 45
= 73
Step2:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
Step3:
LCM(1, 19) = 19
GCD(1, 19) = ( 1 x 19 ) / 19
= 1 / 19
= 1
So, Greatest Common Divisor of 73, 45, 70, 19 is 1
