Given numbers are 158, 660, 409, 695

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

Apply this formula for all numbers.

Step1:

LCM(158, 660) = 52140

GCD(158, 660) = ( 158 x 660 ) / 52140

= 158 / 660

= 158

Step2:

LCM(2, 409) = 818

GCD(2, 409) = ( 2 x 409 ) / 818

= 2 / 409

= 2

Step3:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

So, Greatest Common Divisor of 158, 660, 409, 695 is 1
