Given numbers are 748, 698, 390, 577
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(748, 698) = 261052
GCD(748, 698) = ( 748 x 698 ) / 261052
= 748 / 698
= 748
Step2:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
Step3:
LCM(2, 577) = 1154
GCD(2, 577) = ( 2 x 577 ) / 1154
= 2 / 577
= 2
So, Greatest Common Divisor of 748, 698, 390, 577 is 1
