HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 667, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 667, 961 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 605, 667, 961 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 605, 667, 961 is 1.
HCF(605, 667, 961) = 1
HCF of 605, 667, 961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 667, 961 is 1.
Highest Common Factor of 605,667,961 is 1
Step 1: Since 667 > 605, we apply the division lemma to 667 and 605, to get
667 = 605 x 1 + 62
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 62 and 605, to get
605 = 62 x 9 + 47
Step 3: We consider the new divisor 62 and the new remainder 47, and apply the division lemma to get
62 = 47 x 1 + 15
We consider the new divisor 47 and the new remainder 15,and apply the division lemma to get
47 = 15 x 3 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 605 and 667 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(47,15) = HCF(62,47) = HCF(605,62) = HCF(667,605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 961 > 1, we apply the division lemma to 961 and 1, to get
961 = 1 x 961 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 961 is 1
Notice that 1 = HCF(961,1) .
