Given numbers are 655, 887, 254, 780

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

Apply this formula for all numbers.

Step1:

LCM(655, 887) = 580985

GCD(655, 887) = ( 655 x 887 ) / 580985

= 655 / 887

= 655

Step2:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 655, 887, 254, 780 is 1
