Given numbers are 655, 190, 978, 125

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

Apply this formula for all numbers.

Step1:

LCM(655, 190) = 24890

GCD(655, 190) = ( 655 x 190 ) / 24890

= 655 / 190

= 655

Step2:

LCM(5, 978) = 4890

GCD(5, 978) = ( 5 x 978 ) / 4890

= 5 / 978

= 5

Step3:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

So, Greatest Common Divisor of 655, 190, 978, 125 is 1
