Given numbers are 821, 240, 100, 841

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 841 are 29 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 821, 240, 100, 841

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

Apply this formula for all numbers.

Step1:

LCM(821, 240) = 197040

GCD(821, 240) = ( 821 x 240 ) / 197040

= 821 / 240

= 821

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

So, Greatest Common Divisor of 821, 240, 100, 841 is 1
