Given numbers are 455, 931, 277, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 931) = 60515
GCD(455, 931) = ( 455 x 931 ) / 60515
= 455 / 931
= 455
Step2:
LCM(7, 277) = 1939
GCD(7, 277) = ( 7 x 277 ) / 1939
= 7 / 277
= 7
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 455, 931, 277, 915 is 1
