Steps to Calculate GCD of 315, 702, 862, 409 using LCM Formula

Given numbers are 315, 702, 862, 409

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

Apply this formula for all numbers.

Step1:

LCM(315, 702) = 24570

GCD(315, 702) = ( 315 x 702 ) / 24570

= 315 / 702

= 315


Step2:

LCM(9, 862) = 7758

GCD(9, 862) = ( 9 x 862 ) / 7758

= 9 / 862

= 9


Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1


So, Greatest Common Divisor of 315, 702, 862, 409 is 1
