Given numbers are 550, 620, 660, 965

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

Apply this formula for all numbers.

Step1:

LCM(550, 620) = 34100

GCD(550, 620) = ( 550 x 620 ) / 34100

= 550 / 620

= 550

Step2:

LCM(10, 660) = 660

GCD(10, 660) = ( 10 x 660 ) / 660

= 10 / 660

= 10

Step3:

LCM(10, 965) = 1930

GCD(10, 965) = ( 10 x 965 ) / 1930

= 10 / 965

= 10

So, Greatest Common Divisor of 550, 620, 660, 965 is 5
