Given numbers are 728, 782, 706, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 782) = 284648
GCD(728, 782) = ( 728 x 782 ) / 284648
= 728 / 782
= 728
Step2:
LCM(2, 706) = 706
GCD(2, 706) = ( 2 x 706 ) / 706
= 2 / 706
= 2
Step3:
LCM(2, 423) = 846
GCD(2, 423) = ( 2 x 423 ) / 846
= 2 / 423
= 2
So, Greatest Common Divisor of 728, 782, 706, 423 is 1
