Given numbers are 744, 830, 558, 289
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(744, 830) = 308760
GCD(744, 830) = ( 744 x 830 ) / 308760
= 744 / 830
= 744
Step2:
LCM(2, 558) = 558
GCD(2, 558) = ( 2 x 558 ) / 558
= 2 / 558
= 2
Step3:
LCM(2, 289) = 578
GCD(2, 289) = ( 2 x 289 ) / 578
= 2 / 289
= 2
So, Greatest Common Divisor of 744, 830, 558, 289 is 1
