HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 134, 642, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 134, 642, 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 134, 642, 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 134, 642, 207 is 1.
HCF(134, 642, 207) = 1
HCF of 134, 642, 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 134, 642, 207 is 1.
Highest Common Factor of 134,642,207 is 1
Step 1: Since 642 > 134, we apply the division lemma to 642 and 134, to get
642 = 134 x 4 + 106
Step 2: Since the reminder 134 ≠ 0, we apply division lemma to 106 and 134, to get
134 = 106 x 1 + 28
Step 3: We consider the new divisor 106 and the new remainder 28, and apply the division lemma to get
106 = 28 x 3 + 22
We consider the new divisor 28 and the new remainder 22,and apply the division lemma to get
28 = 22 x 1 + 6
We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get
22 = 6 x 3 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 134 and 642 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(28,22) = HCF(106,28) = HCF(134,106) = HCF(642,134) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 207 > 2, we apply the division lemma to 207 and 2, to get
207 = 2 x 103 + 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 207 is 1
Notice that 1 = HCF(2,1) = HCF(207,2) .
