Steps to Calculate GCD of 978, 486, 498, 805 using LCM Formula

Given numbers are 978, 486, 498, 805

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

Apply this formula for all numbers.

Step1:

LCM(978, 486) = 79218

GCD(978, 486) = ( 978 x 486 ) / 79218

= 978 / 486

= 978


Step2:

LCM(6, 498) = 498

GCD(6, 498) = ( 6 x 498 ) / 498

= 6 / 498

= 6


Step3:

LCM(6, 805) = 4830

GCD(6, 805) = ( 6 x 805 ) / 4830

= 6 / 805

= 6


So, Greatest Common Divisor of 978, 486, 498, 805 is 1
