Given numbers are 158, 978, 445, 625

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

Apply this formula for all numbers.

Step1:

LCM(158, 978) = 77262

GCD(158, 978) = ( 158 x 978 ) / 77262

= 158 / 978

= 158

Step2:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

Step3:

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

= 1 / 625

= 1

So, Greatest Common Divisor of 158, 978, 445, 625 is 1
