Given numbers are 978, 427, 889, 651

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

Apply this formula for all numbers.

Step1:

LCM(978, 427) = 417606

GCD(978, 427) = ( 978 x 427 ) / 417606

= 978 / 427

= 978

Step2:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1

Step3:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 978, 427, 889, 651 is 1
