HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 865, 726 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 406, 865, 726 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 406, 865, 726 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 406, 865, 726 is 1.
HCF(406, 865, 726) = 1
HCF of 406, 865, 726 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 406, 865, 726 is 1.
Highest Common Factor of 406,865,726 is 1
Step 1: Since 865 > 406, we apply the division lemma to 865 and 406, to get
865 = 406 x 2 + 53
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 53 and 406, to get
406 = 53 x 7 + 35
Step 3: We consider the new divisor 53 and the new remainder 35, and apply the division lemma to get
53 = 35 x 1 + 18
We consider the new divisor 35 and the new remainder 18,and apply the division lemma to get
35 = 18 x 1 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 406 and 865 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(35,18) = HCF(53,35) = HCF(406,53) = HCF(865,406) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 726 > 1, we apply the division lemma to 726 and 1, to get
726 = 1 x 726 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 726 is 1
Notice that 1 = HCF(726,1) .
