HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 799, 8645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 799, 8645 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 799, 8645 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 799, 8645 is 1.
HCF(799, 8645) = 1
HCF of 799, 8645 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 799, 8645 is 1.
Highest Common Factor of 799,8645 is 1
Step 1: Since 8645 > 799, we apply the division lemma to 8645 and 799, to get
8645 = 799 x 10 + 655
Step 2: Since the reminder 799 ≠ 0, we apply division lemma to 655 and 799, to get
799 = 655 x 1 + 144
Step 3: We consider the new divisor 655 and the new remainder 144, and apply the division lemma to get
655 = 144 x 4 + 79
We consider the new divisor 144 and the new remainder 79,and apply the division lemma to get
144 = 79 x 1 + 65
We consider the new divisor 79 and the new remainder 65,and apply the division lemma to get
79 = 65 x 1 + 14
We consider the new divisor 65 and the new remainder 14,and apply the division lemma to get
65 = 14 x 4 + 9
We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get
14 = 9 x 1 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 799 and 8645 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(65,14) = HCF(79,65) = HCF(144,79) = HCF(655,144) = HCF(799,655) = HCF(8645,799) .
