Given numbers are 490, 965, 805, 351

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

Apply this formula for all numbers.

Step1:

LCM(490, 965) = 94570

GCD(490, 965) = ( 490 x 965 ) / 94570

= 490 / 965

= 490

Step2:

LCM(5, 805) = 805

GCD(5, 805) = ( 5 x 805 ) / 805

= 5 / 805

= 5

Step3:

LCM(5, 351) = 1755

GCD(5, 351) = ( 5 x 351 ) / 1755

= 5 / 351

= 5

So, Greatest Common Divisor of 490, 965, 805, 351 is 1
