HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 957, 213, 969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 803, 957, 213, 969 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 803, 957, 213, 969 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 803, 957, 213, 969 is 1.
HCF(803, 957, 213, 969) = 1
HCF of 803, 957, 213, 969 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 803, 957, 213, 969 is 1.
Highest Common Factor of 803,957,213,969 is 1
Step 1: Since 957 > 803, we apply the division lemma to 957 and 803, to get
957 = 803 x 1 + 154
Step 2: Since the reminder 803 ≠ 0, we apply division lemma to 154 and 803, to get
803 = 154 x 5 + 33
Step 3: We consider the new divisor 154 and the new remainder 33, and apply the division lemma to get
154 = 33 x 4 + 22
We consider the new divisor 33 and the new remainder 22,and apply the division lemma to get
33 = 22 x 1 + 11
We consider the new divisor 22 and the new remainder 11,and apply the division lemma to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 803 and 957 is 11
Notice that 11 = HCF(22,11) = HCF(33,22) = HCF(154,33) = HCF(803,154) = HCF(957,803) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 213 > 11, we apply the division lemma to 213 and 11, to get
213 = 11 x 19 + 4
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 4 and 11, to get
11 = 4 x 2 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 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 11 and 213 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(213,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 969 > 1, we apply the division lemma to 969 and 1, to get
969 = 1 x 969 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 969 is 1
Notice that 1 = HCF(969,1) .
