HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 463, 798 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 463, 798 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 463, 798 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 463, 798 is 1.
HCF(463, 798) = 1
HCF of 463, 798 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 463, 798 is 1.
Highest Common Factor of 463,798 is 1
Step 1: Since 798 > 463, we apply the division lemma to 798 and 463, to get
798 = 463 x 1 + 335
Step 2: Since the reminder 463 ≠ 0, we apply division lemma to 335 and 463, to get
463 = 335 x 1 + 128
Step 3: We consider the new divisor 335 and the new remainder 128, and apply the division lemma to get
335 = 128 x 2 + 79
We consider the new divisor 128 and the new remainder 79,and apply the division lemma to get
128 = 79 x 1 + 49
We consider the new divisor 79 and the new remainder 49,and apply the division lemma to get
79 = 49 x 1 + 30
We consider the new divisor 49 and the new remainder 30,and apply the division lemma to get
49 = 30 x 1 + 19
We consider the new divisor 30 and the new remainder 19,and apply the division lemma to get
30 = 19 x 1 + 11
We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get
19 = 11 x 1 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 463 and 798 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(30,19) = HCF(49,30) = HCF(79,49) = HCF(128,79) = HCF(335,128) = HCF(463,335) = HCF(798,463) .
