Given numbers are 515, 633, 864, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 633) = 325995
GCD(515, 633) = ( 515 x 633 ) / 325995
= 515 / 633
= 515
Step2:
LCM(1, 864) = 864
GCD(1, 864) = ( 1 x 864 ) / 864
= 1 / 864
= 1
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 515, 633, 864, 390 is 1
