Given numbers are 646, 612, 723, 162

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

Apply this formula for all numbers.

Step1:

LCM(646, 612) = 11628

GCD(646, 612) = ( 646 x 612 ) / 11628

= 646 / 612

= 646

Step2:

LCM(34, 723) = 24582

GCD(34, 723) = ( 34 x 723 ) / 24582

= 34 / 723

= 34

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 646, 612, 723, 162 is 1
