Given numbers are 440, 189, 821, 103

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(440, 189) = 83160

GCD(440, 189) = ( 440 x 189 ) / 83160

= 440 / 189

= 440

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

= 1 / 103

= 1

So, Greatest Common Divisor of 440, 189, 821, 103 is 1
