GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 383) = 310613
GCD(811, 383) = ( 811 x 383 ) / 310613
= 811 / 383
= 811
Step2:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
Step3:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
So, Greatest Common Divisor of 811, 383, 285, 784 is 1
