Given numbers are 399, 671, 722, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 671) = 267729
GCD(399, 671) = ( 399 x 671 ) / 267729
= 399 / 671
= 399
Step2:
LCM(1, 722) = 722
GCD(1, 722) = ( 1 x 722 ) / 722
= 1 / 722
= 1
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 399, 671, 722, 787 is 1
