Given numbers are 978, 648, 653, 792

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

Apply this formula for all numbers.

Step1:

LCM(978, 648) = 105624

GCD(978, 648) = ( 978 x 648 ) / 105624

= 978 / 648

= 978

Step2:

LCM(6, 653) = 3918

GCD(6, 653) = ( 6 x 653 ) / 3918

= 6 / 653

= 6

Step3:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1

So, Greatest Common Divisor of 978, 648, 653, 792 is 1
