Given numbers are 155, 275, 880, 660

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

Apply this formula for all numbers.

Step1:

LCM(155, 275) = 8525

GCD(155, 275) = ( 155 x 275 ) / 8525

= 155 / 275

= 155

Step2:

LCM(5, 880) = 880

GCD(5, 880) = ( 5 x 880 ) / 880

= 5 / 880

= 5

Step3:

LCM(5, 660) = 660

GCD(5, 660) = ( 5 x 660 ) / 660

= 5 / 660

= 5

So, Greatest Common Divisor of 155, 275, 880, 660 is 5
