Given numbers are 915, 258, 109, 325
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 258) = 78690
GCD(915, 258) = ( 915 x 258 ) / 78690
= 915 / 258
= 915
Step2:
LCM(3, 109) = 327
GCD(3, 109) = ( 3 x 109 ) / 327
= 3 / 109
= 3
Step3:
LCM(1, 325) = 325
GCD(1, 325) = ( 1 x 325 ) / 325
= 1 / 325
= 1
So, Greatest Common Divisor of 915, 258, 109, 325 is 1
