Given numbers are 709, 651, 203, 978

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

Apply this formula for all numbers.

Step1:

LCM(709, 651) = 461559

GCD(709, 651) = ( 709 x 651 ) / 461559

= 709 / 651

= 709

Step2:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 709, 651, 203, 978 is 1
