Given numbers are 130, 790, 398, 503
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 790) = 10270
GCD(130, 790) = ( 130 x 790 ) / 10270
= 130 / 790
= 130
Step2:
LCM(10, 398) = 1990
GCD(10, 398) = ( 10 x 398 ) / 1990
= 10 / 398
= 10
Step3:
LCM(2, 503) = 1006
GCD(2, 503) = ( 2 x 503 ) / 1006
= 2 / 503
= 2
So, Greatest Common Divisor of 130, 790, 398, 503 is 1
