GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(748, 143) = 9724
GCD(748, 143) = ( 748 x 143 ) / 9724
= 748 / 143
= 748
Step2:
LCM(11, 128) = 1408
GCD(11, 128) = ( 11 x 128 ) / 1408
= 11 / 128
= 11
Step3:
LCM(1, 559) = 559
GCD(1, 559) = ( 1 x 559 ) / 559
= 1 / 559
= 1
So, Greatest Common Divisor of 748, 143, 128, 559 is 1
