Given numbers are 818, 138, 440, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(818, 138) = 56442
GCD(818, 138) = ( 818 x 138 ) / 56442
= 818 / 138
= 818
Step2:
LCM(2, 440) = 440
GCD(2, 440) = ( 2 x 440 ) / 440
= 2 / 440
= 2
Step3:
LCM(2, 445) = 890
GCD(2, 445) = ( 2 x 445 ) / 890
= 2 / 445
= 2
So, Greatest Common Divisor of 818, 138, 440, 445 is 1
