Given numbers are 807, 380, 445, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(807, 380) = 306660
GCD(807, 380) = ( 807 x 380 ) / 306660
= 807 / 380
= 807
Step2:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 807, 380, 445, 638 is 1
