Given numbers are 234, 780, 855, 348
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(234, 780) = 2340
GCD(234, 780) = ( 234 x 780 ) / 2340
= 234 / 780
= 234
Step2:
LCM(78, 855) = 22230
GCD(78, 855) = ( 78 x 855 ) / 22230
= 78 / 855
= 78
Step3:
LCM(3, 348) = 348
GCD(3, 348) = ( 3 x 348 ) / 348
= 3 / 348
= 3
So, Greatest Common Divisor of 234, 780, 855, 348 is 3
