Given numbers are 275, 890, 977, 815

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

Apply this formula for all numbers.

Step1:

LCM(275, 890) = 48950

GCD(275, 890) = ( 275 x 890 ) / 48950

= 275 / 890

= 275

Step2:

LCM(5, 977) = 4885

GCD(5, 977) = ( 5 x 977 ) / 4885

= 5 / 977

= 5

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 275, 890, 977, 815 is 1
