Given numbers are 430, 690, 658, 502

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

Apply this formula for all numbers.

Step1:

LCM(430, 690) = 29670

GCD(430, 690) = ( 430 x 690 ) / 29670

= 430 / 690

= 430

Step2:

LCM(10, 658) = 3290

GCD(10, 658) = ( 10 x 658 ) / 3290

= 10 / 658

= 10

Step3:

LCM(2, 502) = 502

GCD(2, 502) = ( 2 x 502 ) / 502

= 2 / 502

= 2

So, Greatest Common Divisor of 430, 690, 658, 502 is 2
