Given numbers are 247, 646, 907, 503

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

Apply this formula for all numbers.

Step1:

LCM(247, 646) = 8398

GCD(247, 646) = ( 247 x 646 ) / 8398

= 247 / 646

= 247

Step2:

LCM(19, 907) = 17233

GCD(19, 907) = ( 19 x 907 ) / 17233

= 19 / 907

= 19

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 247, 646, 907, 503 is 1
