Given numbers are 915, 295, 129, 803
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 295) = 53985
GCD(915, 295) = ( 915 x 295 ) / 53985
= 915 / 295
= 915
Step2:
LCM(5, 129) = 645
GCD(5, 129) = ( 5 x 129 ) / 645
= 5 / 129
= 5
Step3:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
So, Greatest Common Divisor of 915, 295, 129, 803 is 1
