HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 361, 772, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 361, 772, 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 825, 361, 772, 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 825, 361, 772, 961 is 1.
HCF(825, 361, 772, 961) = 1
HCF of 825, 361, 772, 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 825, 361, 772, 961 is 1.
Highest Common Factor of 825,361,772,961 is 1
Step 1: Since 825 > 361, we apply the division lemma to 825 and 361, to get
825 = 361 x 2 + 103
Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 103 and 361, to get
361 = 103 x 3 + 52
Step 3: We consider the new divisor 103 and the new remainder 52, and apply the division lemma to get
103 = 52 x 1 + 51
We consider the new divisor 52 and the new remainder 51,and apply the division lemma to get
52 = 51 x 1 + 1
We consider the new divisor 51 and the new remainder 1,and apply the division lemma to get
51 = 1 x 51 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 825 and 361 is 1
Notice that 1 = HCF(51,1) = HCF(52,51) = HCF(103,52) = HCF(361,103) = HCF(825,361) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 772 > 1, we apply the division lemma to 772 and 1, to get
772 = 1 x 772 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 772 is 1
Notice that 1 = HCF(772,1) .
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) .
