Given numbers are 690, 999, 79, 538

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

Apply this formula for all numbers.

Step1:

LCM(690, 999) = 229770

GCD(690, 999) = ( 690 x 999 ) / 229770

= 690 / 999

= 690

Step2:

LCM(3, 79) = 237

GCD(3, 79) = ( 3 x 79 ) / 237

= 3 / 79

= 3

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 690, 999, 79, 538 is 1
