HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 651, 863 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 651, 863 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 909, 651, 863 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 909, 651, 863 is 1.
HCF(909, 651, 863) = 1
HCF of 909, 651, 863 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 651, 863 is 1.
Highest Common Factor of 909,651,863 is 1
Step 1: Since 909 > 651, we apply the division lemma to 909 and 651, to get
909 = 651 x 1 + 258
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 258 and 651, to get
651 = 258 x 2 + 135
Step 3: We consider the new divisor 258 and the new remainder 135, and apply the division lemma to get
258 = 135 x 1 + 123
We consider the new divisor 135 and the new remainder 123,and apply the division lemma to get
135 = 123 x 1 + 12
We consider the new divisor 123 and the new remainder 12,and apply the division lemma to get
123 = 12 x 10 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 909 and 651 is 3
Notice that 3 = HCF(12,3) = HCF(123,12) = HCF(135,123) = HCF(258,135) = HCF(651,258) = HCF(909,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 863 > 3, we apply the division lemma to 863 and 3, to get
863 = 3 x 287 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 863 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(863,3) .
