Given numbers are 989, 780, 194, 503

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

Apply this formula for all numbers.

Step1:

LCM(989, 780) = 771420

GCD(989, 780) = ( 989 x 780 ) / 771420

= 989 / 780

= 989

Step2:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

Step3:

LCM(1, 503) = 503

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

= 1 / 503

= 1

So, Greatest Common Divisor of 989, 780, 194, 503 is 1
