HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 779, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 447, 779, 805 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 447, 779, 805 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 447, 779, 805 is 1.
HCF(447, 779, 805) = 1
HCF of 447, 779, 805 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 447, 779, 805 is 1.
Highest Common Factor of 447,779,805 is 1
Step 1: Since 779 > 447, we apply the division lemma to 779 and 447, to get
779 = 447 x 1 + 332
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 332 and 447, to get
447 = 332 x 1 + 115
Step 3: We consider the new divisor 332 and the new remainder 115, and apply the division lemma to get
332 = 115 x 2 + 102
We consider the new divisor 115 and the new remainder 102,and apply the division lemma to get
115 = 102 x 1 + 13
We consider the new divisor 102 and the new remainder 13,and apply the division lemma to get
102 = 13 x 7 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 447 and 779 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(102,13) = HCF(115,102) = HCF(332,115) = HCF(447,332) = HCF(779,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 805 > 1, we apply the division lemma to 805 and 1, to get
805 = 1 x 805 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 805 is 1
Notice that 1 = HCF(805,1) .
