Given numbers are 721, 707, 703, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 707) = 72821
GCD(721, 707) = ( 721 x 707 ) / 72821
= 721 / 707
= 721
Step2:
LCM(7, 703) = 4921
GCD(7, 703) = ( 7 x 703 ) / 4921
= 7 / 703
= 7
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 721, 707, 703, 485 is 1
