Given numbers are 230, 842, 687, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(230, 842) = 96830
GCD(230, 842) = ( 230 x 842 ) / 96830
= 230 / 842
= 230
Step2:
LCM(2, 687) = 1374
GCD(2, 687) = ( 2 x 687 ) / 1374
= 2 / 687
= 2
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 230, 842, 687, 830 is 1
