GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 824) = 366680
GCD(445, 824) = ( 445 x 824 ) / 366680
= 445 / 824
= 445
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 997) = 997
GCD(1, 997) = ( 1 x 997 ) / 997
= 1 / 997
= 1
So, Greatest Common Divisor of 445, 824, 128, 997 is 1
