Given numbers are 798, 978, 92, 821

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

Apply this formula for all numbers.

Step1:

LCM(798, 978) = 130074

GCD(798, 978) = ( 798 x 978 ) / 130074

= 798 / 978

= 798

Step2:

LCM(6, 92) = 276

GCD(6, 92) = ( 6 x 92 ) / 276

= 6 / 92

= 6

Step3:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

So, Greatest Common Divisor of 798, 978, 92, 821 is 1
