Steps to Calculate GCD of 991, 509, 878, 800 using LCM Formula

Given numbers are 991, 509, 878, 800

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

Apply this formula for all numbers.

Step1:

LCM(991, 509) = 504419

GCD(991, 509) = ( 991 x 509 ) / 504419

= 991 / 509

= 991


Step2:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1


Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1
