HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 401, 682, 858 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 401, 682, 858 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 401, 682, 858 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 401, 682, 858 is 1.
HCF(401, 682, 858) = 1
HCF of 401, 682, 858 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 401, 682, 858 is 1.
Highest Common Factor of 401,682,858 is 1
Step 1: Since 682 > 401, we apply the division lemma to 682 and 401, to get
682 = 401 x 1 + 281
Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 281 and 401, to get
401 = 281 x 1 + 120
Step 3: We consider the new divisor 281 and the new remainder 120, and apply the division lemma to get
281 = 120 x 2 + 41
We consider the new divisor 120 and the new remainder 41,and apply the division lemma to get
120 = 41 x 2 + 38
We consider the new divisor 41 and the new remainder 38,and apply the division lemma to get
41 = 38 x 1 + 3
We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get
38 = 3 x 12 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 401 and 682 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(41,38) = HCF(120,41) = HCF(281,120) = HCF(401,281) = HCF(682,401) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 858 > 1, we apply the division lemma to 858 and 1, to get
858 = 1 x 858 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 858 is 1
Notice that 1 = HCF(858,1) .
