HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 499 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 705, 499 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 705, 499 is 1.
HCF(705, 499) = 1
HCF of 705, 499 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 499 is 1.
Highest Common Factor of 705,499 is 1
Step 1: Since 705 > 499, we apply the division lemma to 705 and 499, to get
705 = 499 x 1 + 206
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 206 and 499, to get
499 = 206 x 2 + 87
Step 3: We consider the new divisor 206 and the new remainder 87, and apply the division lemma to get
206 = 87 x 2 + 32
We consider the new divisor 87 and the new remainder 32,and apply the division lemma to get
87 = 32 x 2 + 23
We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get
32 = 23 x 1 + 9
We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get
23 = 9 x 2 + 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 705 and 499 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(87,32) = HCF(206,87) = HCF(499,206) = HCF(705,499) .
