Steps to Calculate GCD of 489, 692, 253, 971 using LCM Formula

Given numbers are 489, 692, 253, 971

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

Apply this formula for all numbers.

Step1:

LCM(489, 692) = 338388

GCD(489, 692) = ( 489 x 692 ) / 338388

= 489 / 692

= 489


Step2:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1


Step3:

LCM(1, 971) = 971

GCD(1, 971) = ( 1 x 971 ) / 971

= 1 / 971

= 1
