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

Apply this formula for all numbers.

Step1:

LCM(642, 776) = 249096

GCD(642, 776) = ( 642 x 776 ) / 249096

= 642 / 776

= 642

Step2:

LCM(2, 999) = 1998

GCD(2, 999) = ( 2 x 999 ) / 1998

= 2 / 999

= 2

Step3:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

So, Greatest Common Divisor of 642, 776, 999, 169 is 1
