GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 428) = 98012
GCD(458, 428) = ( 458 x 428 ) / 98012
= 458 / 428
= 458
Step2:
LCM(2, 756) = 756
GCD(2, 756) = ( 2 x 756 ) / 756
= 2 / 756
= 2
Step3:
LCM(2, 755) = 1510
GCD(2, 755) = ( 2 x 755 ) / 1510
= 2 / 755
= 2
So, Greatest Common Divisor of 458, 428, 756, 755 is 1
