GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(273, 861) = 11193
GCD(273, 861) = ( 273 x 861 ) / 11193
= 273 / 861
= 273
Step2:
LCM(21, 429) = 3003
GCD(21, 429) = ( 21 x 429 ) / 3003
= 21 / 429
= 21
Step3:
LCM(3, 783) = 783
GCD(3, 783) = ( 3 x 783 ) / 783
= 3 / 783
= 3
So, Greatest Common Divisor of 273, 861, 429, 783 is 3
