Given numbers are 161, 812, 623, 490

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

Apply this formula for all numbers.

Step1:

LCM(161, 812) = 18676

GCD(161, 812) = ( 161 x 812 ) / 18676

= 161 / 812

= 161

Step2:

LCM(7, 623) = 623

GCD(7, 623) = ( 7 x 623 ) / 623

= 7 / 623

= 7

Step3:

LCM(7, 490) = 490

GCD(7, 490) = ( 7 x 490 ) / 490

= 7 / 490

= 7

So, Greatest Common Divisor of 161, 812, 623, 490 is 7
