Given numbers are 169, 458, 811, 642

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

Apply this formula for all numbers.

Step1:

LCM(169, 458) = 77402

GCD(169, 458) = ( 169 x 458 ) / 77402

= 169 / 458

= 169

Step2:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 169, 458, 811, 642 is 1
