HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 669, 813, 887 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 669, 813, 887 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 669, 813, 887 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 669, 813, 887 is 1.
HCF(669, 813, 887) = 1
HCF of 669, 813, 887 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 669, 813, 887 is 1.
Highest Common Factor of 669,813,887 is 1
Step 1: Since 813 > 669, we apply the division lemma to 813 and 669, to get
813 = 669 x 1 + 144
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 144 and 669, to get
669 = 144 x 4 + 93
Step 3: We consider the new divisor 144 and the new remainder 93, and apply the division lemma to get
144 = 93 x 1 + 51
We consider the new divisor 93 and the new remainder 51,and apply the division lemma to get
93 = 51 x 1 + 42
We consider the new divisor 51 and the new remainder 42,and apply the division lemma to get
51 = 42 x 1 + 9
We consider the new divisor 42 and the new remainder 9,and apply the division lemma to get
42 = 9 x 4 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 669 and 813 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(42,9) = HCF(51,42) = HCF(93,51) = HCF(144,93) = HCF(669,144) = HCF(813,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 887 > 3, we apply the division lemma to 887 and 3, to get
887 = 3 x 295 + 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 887 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(887,3) .
