Steps to Calculate GCD of 170, 291, 79, 345 using LCM Formula
Given numbers are 170, 291, 79, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 291) = 49470
GCD(170, 291) = ( 170 x 291 ) / 49470
= 170 / 291
= 170
Step2:
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
= 1 / 79
= 1
Step3:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
So, Greatest Common Divisor of 170, 291, 79, 345 is 1
