Given numbers are 978, 659, 207, 551

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

Apply this formula for all numbers.

Step1:

LCM(978, 659) = 644502

GCD(978, 659) = ( 978 x 659 ) / 644502

= 978 / 659

= 978

Step2:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 978, 659, 207, 551 is 1
