GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 130) = 23530
GCD(905, 130) = ( 905 x 130 ) / 23530
= 905 / 130
= 905
Step2:
LCM(5, 915) = 915
GCD(5, 915) = ( 5 x 915 ) / 915
= 5 / 915
= 5
Step3:
LCM(5, 290) = 290
GCD(5, 290) = ( 5 x 290 ) / 290
= 5 / 290
= 5
So, Greatest Common Divisor of 905, 130, 915, 290 is 5
