Given numbers are 247, 689, 674, 919

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

Apply this formula for all numbers.

Step1:

LCM(247, 689) = 13091

GCD(247, 689) = ( 247 x 689 ) / 13091

= 247 / 689

= 247

Step2:

LCM(13, 674) = 8762

GCD(13, 674) = ( 13 x 674 ) / 8762

= 13 / 674

= 13

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 247, 689, 674, 919 is 1
