Given numbers are 490, 371, 857, 315

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

Apply this formula for all numbers.

Step1:

LCM(490, 371) = 25970

GCD(490, 371) = ( 490 x 371 ) / 25970

= 490 / 371

= 490

Step2:

LCM(7, 857) = 5999

GCD(7, 857) = ( 7 x 857 ) / 5999

= 7 / 857

= 7

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 490, 371, 857, 315 is 1
