Given numbers are 490, 974, 30, 635

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

Apply this formula for all numbers.

Step1:

LCM(490, 974) = 238630

GCD(490, 974) = ( 490 x 974 ) / 238630

= 490 / 974

= 490

Step2:

LCM(2, 30) = 30

GCD(2, 30) = ( 2 x 30 ) / 30

= 2 / 30

= 2

Step3:

LCM(2, 635) = 1270

GCD(2, 635) = ( 2 x 635 ) / 1270

= 2 / 635

= 2

So, Greatest Common Divisor of 490, 974, 30, 635 is 1
