Given numbers are 698, 258, 290, 458

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

Apply this formula for all numbers.

Step1:

LCM(698, 258) = 90042

GCD(698, 258) = ( 698 x 258 ) / 90042

= 698 / 258

= 698

Step2:

LCM(2, 290) = 290

GCD(2, 290) = ( 2 x 290 ) / 290

= 2 / 290

= 2

Step3:

LCM(2, 458) = 458

GCD(2, 458) = ( 2 x 458 ) / 458

= 2 / 458

= 2

So, Greatest Common Divisor of 698, 258, 290, 458 is 2
