Steps to Calculate GCD of 105, 247, 579, 686 using LCM Formula

Given numbers are 105, 247, 579, 686

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(105, 247) = 25935

GCD(105, 247) = ( 105 x 247 ) / 25935

= 105 / 247

= 105


Step2:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1


Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1


So, Greatest Common Divisor of 105, 247, 579, 686 is 1
