Given numbers are 748, 561, 288, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(748, 561) = 2244
GCD(748, 561) = ( 748 x 561 ) / 2244
= 748 / 561
= 748
Step2:
LCM(187, 288) = 53856
GCD(187, 288) = ( 187 x 288 ) / 53856
= 187 / 288
= 187
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 748, 561, 288, 830 is 1
