HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 646, 699, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 646, 699, 207 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 646, 699, 207 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 646, 699, 207 is 1.
HCF(646, 699, 207) = 1
HCF of 646, 699, 207 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 646, 699, 207 is 1.
Highest Common Factor of 646,699,207 is 1
Step 1: Since 699 > 646, we apply the division lemma to 699 and 646, to get
699 = 646 x 1 + 53
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 53 and 646, to get
646 = 53 x 12 + 10
Step 3: We consider the new divisor 53 and the new remainder 10, and apply the division lemma to get
53 = 10 x 5 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 646 and 699 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(53,10) = HCF(646,53) = HCF(699,646) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 207 > 1, we apply the division lemma to 207 and 1, to get
207 = 1 x 207 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 207 is 1
Notice that 1 = HCF(207,1) .
