Given numbers are 147, 638, 551, 209

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

Apply this formula for all numbers.

Step1:

LCM(147, 638) = 93786

GCD(147, 638) = ( 147 x 638 ) / 93786

= 147 / 638

= 147

Step2:

LCM(1, 551) = 551

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

= 1 / 551

= 1

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 147, 638, 551, 209 is 1
