HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 444, 67 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 444, 67 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, 444, 67 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, 444, 67 is 1.
HCF(670, 444, 67) = 1
HCF of 670, 444, 67 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, 444, 67 is 1.
Highest Common Factor of 670,444,67 is 1
Step 1: Since 670 > 444, we apply the division lemma to 670 and 444, to get
670 = 444 x 1 + 226
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 226 and 444, to get
444 = 226 x 1 + 218
Step 3: We consider the new divisor 226 and the new remainder 218, and apply the division lemma to get
226 = 218 x 1 + 8
We consider the new divisor 218 and the new remainder 8,and apply the division lemma to get
218 = 8 x 27 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 670 and 444 is 2
Notice that 2 = HCF(8,2) = HCF(218,8) = HCF(226,218) = HCF(444,226) = HCF(670,444) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 67 > 2, we apply the division lemma to 67 and 2, to get
67 = 2 x 33 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 67 is 1
Notice that 1 = HCF(2,1) = HCF(67,2) .
