Given numbers are 170, 707, 729, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 707) = 120190
GCD(170, 707) = ( 170 x 707 ) / 120190
= 170 / 707
= 170
Step2:
LCM(1, 729) = 729
GCD(1, 729) = ( 1 x 729 ) / 729
= 1 / 729
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 170, 707, 729, 457 is 1
