GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 155) = 14105
GCD(455, 155) = ( 455 x 155 ) / 14105
= 455 / 155
= 455
Step2:
LCM(5, 130) = 130
GCD(5, 130) = ( 5 x 130 ) / 130
= 5 / 130
= 5
Step3:
LCM(5, 915) = 915
GCD(5, 915) = ( 5 x 915 ) / 915
= 5 / 915
= 5
So, Greatest Common Divisor of 455, 155, 130, 915 is 5
