Given numbers are 663, 238, 815, 510
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 238) = 9282
GCD(663, 238) = ( 663 x 238 ) / 9282
= 663 / 238
= 663
Step2:
LCM(17, 815) = 13855
GCD(17, 815) = ( 17 x 815 ) / 13855
= 17 / 815
= 17
Step3:
LCM(1, 510) = 510
GCD(1, 510) = ( 1 x 510 ) / 510
= 1 / 510
= 1
So, Greatest Common Divisor of 663, 238, 815, 510 is 1
