HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 995, 308 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 995, 308 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, 995, 308 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, 995, 308 is 1.
HCF(705, 995, 308) = 1
HCF of 705, 995, 308 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, 995, 308 is 1.
Highest Common Factor of 705,995,308 is 1
Step 1: Since 995 > 705, we apply the division lemma to 995 and 705, to get
995 = 705 x 1 + 290
Step 2: Since the reminder 705 ≠ 0, we apply division lemma to 290 and 705, to get
705 = 290 x 2 + 125
Step 3: We consider the new divisor 290 and the new remainder 125, and apply the division lemma to get
290 = 125 x 2 + 40
We consider the new divisor 125 and the new remainder 40,and apply the division lemma to get
125 = 40 x 3 + 5
We consider the new divisor 40 and the new remainder 5,and apply the division lemma to get
40 = 5 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 705 and 995 is 5
Notice that 5 = HCF(40,5) = HCF(125,40) = HCF(290,125) = HCF(705,290) = HCF(995,705) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 308 > 5, we apply the division lemma to 308 and 5, to get
308 = 5 x 61 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 308 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(308,5) .
