Steps to Calculate GCD of 105, 645, 362, 817 using LCM Formula
Given numbers are 105, 645, 362, 817
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 645) = 4515
GCD(105, 645) = ( 105 x 645 ) / 4515
= 105 / 645
= 105
Step2:
LCM(15, 362) = 5430
GCD(15, 362) = ( 15 x 362 ) / 5430
= 15 / 362
= 15
Step3:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
So, Greatest Common Divisor of 105, 645, 362, 817 is 1
