Given numbers are 991, 708, 861, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 708) = 701628
GCD(991, 708) = ( 991 x 708 ) / 701628
= 991 / 708
= 991
Step2:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
Step3:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
So, Greatest Common Divisor of 991, 708, 861, 403 is 1
