HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 353, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 353, 86 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 670, 353, 86 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 670, 353, 86 is 1.
HCF(670, 353, 86) = 1
HCF of 670, 353, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 353, 86 is 1.
Highest Common Factor of 670,353,86 is 1
Step 1: Since 670 > 353, we apply the division lemma to 670 and 353, to get
670 = 353 x 1 + 317
Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 317 and 353, to get
353 = 317 x 1 + 36
Step 3: We consider the new divisor 317 and the new remainder 36, and apply the division lemma to get
317 = 36 x 8 + 29
We consider the new divisor 36 and the new remainder 29,and apply the division lemma to get
36 = 29 x 1 + 7
We consider the new divisor 29 and the new remainder 7,and apply the division lemma to get
29 = 7 x 4 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 670 and 353 is 1
Notice that 1 = HCF(7,1) = HCF(29,7) = HCF(36,29) = HCF(317,36) = HCF(353,317) = HCF(670,353) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
