Given numbers are 445, 398, 981, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 398) = 177110
GCD(445, 398) = ( 445 x 398 ) / 177110
= 445 / 398
= 445
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
So, Greatest Common Divisor of 445, 398, 981, 807 is 1
