Given numbers are 840, 712, 543, 611

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 712 are 2 x 2 x 2 x 89

Prime factors of 543 are 3 x 181

Prime factors of 611 are 13 x 47

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

Given numbers are 840, 712, 543, 611

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

Apply this formula for all numbers.

Step1:

LCM(840, 712) = 74760

GCD(840, 712) = ( 840 x 712 ) / 74760

= 840 / 712

= 840

Step2:

LCM(8, 543) = 4344

GCD(8, 543) = ( 8 x 543 ) / 4344

= 8 / 543

= 8

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 840, 712, 543, 611 is 1
