Given numbers are 921, 455, 784, 752
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 455) = 419055
GCD(921, 455) = ( 921 x 455 ) / 419055
= 921 / 455
= 921
Step2:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
Step3:
LCM(1, 752) = 752
GCD(1, 752) = ( 1 x 752 ) / 752
= 1 / 752
= 1
So, Greatest Common Divisor of 921, 455, 784, 752 is 1
