HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 216, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 216, 406 is 1 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 825, 216, 406 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 825, 216, 406 is 1.
HCF(825, 216, 406) = 1
HCF of 825, 216, 406 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 216, 406 is 1.
Highest Common Factor of 825,216,406 is 1
Step 1: Since 825 > 216, we apply the division lemma to 825 and 216, to get
825 = 216 x 3 + 177
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 177 and 216, to get
216 = 177 x 1 + 39
Step 3: We consider the new divisor 177 and the new remainder 39, and apply the division lemma to get
177 = 39 x 4 + 21
We consider the new divisor 39 and the new remainder 21,and apply the division lemma to get
39 = 21 x 1 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 825 and 216 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(39,21) = HCF(177,39) = HCF(216,177) = HCF(825,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 3, we apply the division lemma to 406 and 3, to get
406 = 3 x 135 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 406 is 1
Notice that 1 = HCF(3,1) = HCF(406,3) .
