Given numbers are 665, 276, 44, 821

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

Apply this formula for all numbers.

Step1:

LCM(665, 276) = 183540

GCD(665, 276) = ( 665 x 276 ) / 183540

= 665 / 276

= 665

Step2:

LCM(1, 44) = 44

GCD(1, 44) = ( 1 x 44 ) / 44

= 1 / 44

= 1

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 665, 276, 44, 821 is 1
