Given numbers are 690, 155, 117, 503

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

Apply this formula for all numbers.

Step1:

LCM(690, 155) = 21390

GCD(690, 155) = ( 690 x 155 ) / 21390

= 690 / 155

= 690

Step2:

LCM(5, 117) = 585

GCD(5, 117) = ( 5 x 117 ) / 585

= 5 / 117

= 5

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 690, 155, 117, 503 is 1
