Given numbers are 938, 912, 864, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(938, 912) = 427728
GCD(938, 912) = ( 938 x 912 ) / 427728
= 938 / 912
= 938
Step2:
LCM(2, 864) = 864
GCD(2, 864) = ( 2 x 864 ) / 864
= 2 / 864
= 2
Step3:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
So, Greatest Common Divisor of 938, 912, 864, 455 is 1
