Given numbers are 728, 429, 660, 835
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 429) = 24024
GCD(728, 429) = ( 728 x 429 ) / 24024
= 728 / 429
= 728
Step2:
LCM(13, 660) = 8580
GCD(13, 660) = ( 13 x 660 ) / 8580
= 13 / 660
= 13
Step3:
LCM(1, 835) = 835
GCD(1, 835) = ( 1 x 835 ) / 835
= 1 / 835
= 1
So, Greatest Common Divisor of 728, 429, 660, 835 is 1
