Given numbers are 690, 647, 599, 842

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

Apply this formula for all numbers.

Step1:

LCM(690, 647) = 446430

GCD(690, 647) = ( 690 x 647 ) / 446430

= 690 / 647

= 690

Step2:

LCM(1, 599) = 599

GCD(1, 599) = ( 1 x 599 ) / 599

= 1 / 599

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 690, 647, 599, 842 is 1
