Given numbers are 690, 402, 492, 496

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

Apply this formula for all numbers.

Step1:

LCM(690, 402) = 46230

GCD(690, 402) = ( 690 x 402 ) / 46230

= 690 / 402

= 690

Step2:

LCM(6, 492) = 492

GCD(6, 492) = ( 6 x 492 ) / 492

= 6 / 492

= 6

Step3:

LCM(6, 496) = 1488

GCD(6, 496) = ( 6 x 496 ) / 1488

= 6 / 496

= 6

So, Greatest Common Divisor of 690, 402, 492, 496 is 2
