Given numbers are 299, 785, 390, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(299, 785) = 234715
GCD(299, 785) = ( 299 x 785 ) / 234715
= 299 / 785
= 299
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 299, 785, 390, 915 is 1
