Given numbers are 445, 945, 717, 948
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 945) = 84105
GCD(445, 945) = ( 445 x 945 ) / 84105
= 445 / 945
= 445
Step2:
LCM(5, 717) = 3585
GCD(5, 717) = ( 5 x 717 ) / 3585
= 5 / 717
= 5
Step3:
LCM(1, 948) = 948
GCD(1, 948) = ( 1 x 948 ) / 948
= 1 / 948
= 1
So, Greatest Common Divisor of 445, 945, 717, 948 is 1
