Given numbers are 978, 868, 194, 921

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

Apply this formula for all numbers.

Step1:

LCM(978, 868) = 424452

GCD(978, 868) = ( 978 x 868 ) / 424452

= 978 / 868

= 978

Step2:

LCM(2, 194) = 194

GCD(2, 194) = ( 2 x 194 ) / 194

= 2 / 194

= 2

Step3:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

So, Greatest Common Divisor of 978, 868, 194, 921 is 1
