HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 933 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 405, 933 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 405, 933 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 405, 933 is 3.
HCF(405, 933) = 3
HCF of 405, 933 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 405, 933 is 3.
Highest Common Factor of 405,933 is 3
Step 1: Since 933 > 405, we apply the division lemma to 933 and 405, to get
933 = 405 x 2 + 123
Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 123 and 405, to get
405 = 123 x 3 + 36
Step 3: We consider the new divisor 123 and the new remainder 36, and apply the division lemma to get
123 = 36 x 3 + 15
We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get
36 = 15 x 2 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 405 and 933 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(123,36) = HCF(405,123) = HCF(933,405) .
