Given numbers are 830, 578, 865, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 578) = 239870
GCD(830, 578) = ( 830 x 578 ) / 239870
= 830 / 578
= 830
Step2:
LCM(2, 865) = 1730
GCD(2, 865) = ( 2 x 865 ) / 1730
= 2 / 865
= 2
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 830, 578, 865, 915 is 1
