Given numbers are 555, 455, 307, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 455) = 50505
GCD(555, 455) = ( 555 x 455 ) / 50505
= 555 / 455
= 555
Step2:
LCM(5, 307) = 1535
GCD(5, 307) = ( 5 x 307 ) / 1535
= 5 / 307
= 5
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 555, 455, 307, 663 is 1
