Steps to Calculate GCD of 280, 161, 170, 170 using LCM Formula
Given numbers are 280, 161, 170, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 161) = 6440
GCD(280, 161) = ( 280 x 161 ) / 6440
= 280 / 161
= 280
Step2:
LCM(7, 170) = 1190
GCD(7, 170) = ( 7 x 170 ) / 1190
= 7 / 170
= 7
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 280, 161, 170, 170 is 1
