Given numbers are 142, 671, 611, 820

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

Apply this formula for all numbers.

Step1:

LCM(142, 671) = 95282

GCD(142, 671) = ( 142 x 671 ) / 95282

= 142 / 671

= 142

Step2:

LCM(1, 611) = 611

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

= 1 / 611

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 142, 671, 611, 820 is 1
