Steps to Calculate GCD of 357, 491, 830, 217 using LCM Formula
Given numbers are 357, 491, 830, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 491) = 175287
GCD(357, 491) = ( 357 x 491 ) / 175287
= 357 / 491
= 357
Step2:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 357, 491, 830, 217 is 1
