Given numbers are 407, 825, 311, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 825) = 30525
GCD(407, 825) = ( 407 x 825 ) / 30525
= 407 / 825
= 407
Step2:
LCM(11, 311) = 3421
GCD(11, 311) = ( 11 x 311 ) / 3421
= 11 / 311
= 11
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 407, 825, 311, 915 is 1
