Given numbers are 542, 550, 821, 166

The list of prime factors of all numbers are

Prime factors of 542 are 2 x 271

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 821 are 821

Prime factors of 166 are 2 x 83

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

Given numbers are 542, 550, 821, 166

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

Apply this formula for all numbers.

Step1:

LCM(542, 550) = 149050

GCD(542, 550) = ( 542 x 550 ) / 149050

= 542 / 550

= 542

Step2:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 542, 550, 821, 166 is 1
