GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(459, 915) = 139995
GCD(459, 915) = ( 459 x 915 ) / 139995
= 459 / 915
= 459
Step2:
LCM(3, 412) = 1236
GCD(3, 412) = ( 3 x 412 ) / 1236
= 3 / 412
= 3
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 459, 915, 412, 257 is 1
