HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 281, 122 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 667, 281, 122 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 667, 281, 122 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 667, 281, 122 is 1.
HCF(667, 281, 122) = 1
HCF of 667, 281, 122 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 667, 281, 122 is 1.
Highest Common Factor of 667,281,122 is 1
Step 1: Since 667 > 281, we apply the division lemma to 667 and 281, to get
667 = 281 x 2 + 105
Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 105 and 281, to get
281 = 105 x 2 + 71
Step 3: We consider the new divisor 105 and the new remainder 71, and apply the division lemma to get
105 = 71 x 1 + 34
We consider the new divisor 71 and the new remainder 34,and apply the division lemma to get
71 = 34 x 2 + 3
We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get
34 = 3 x 11 + 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 667 and 281 is 1
Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(71,34) = HCF(105,71) = HCF(281,105) = HCF(667,281) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 122 > 1, we apply the division lemma to 122 and 1, to get
122 = 1 x 122 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 122 is 1
Notice that 1 = HCF(122,1) .
