Steps to Calculate GCD of 870, 487, 770, 823 using LCM Formula

Given numbers are 870, 487, 770, 823

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

Apply this formula for all numbers.

Step1:

LCM(870, 487) = 423690

GCD(870, 487) = ( 870 x 487 ) / 423690

= 870 / 487

= 870


Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1


Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1


So, Greatest Common Divisor of 870, 487, 770, 823 is 1
