Given numbers are 445, 921, 376, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 921) = 409845
GCD(445, 921) = ( 445 x 921 ) / 409845
= 445 / 921
= 445
Step2:
LCM(1, 376) = 376
GCD(1, 376) = ( 1 x 376 ) / 376
= 1 / 376
= 1
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 445, 921, 376, 831 is 1
