HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 705 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 705 is 5 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 905, 705 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 905, 705 is 5.
HCF(905, 705) = 5
HCF of 905, 705 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 905, 705 is 5.
Highest Common Factor of 905,705 is 5
Step 1: Since 905 > 705, we apply the division lemma to 905 and 705, to get
905 = 705 x 1 + 200
Step 2: Since the reminder 705 ≠ 0, we apply division lemma to 200 and 705, to get
705 = 200 x 3 + 105
Step 3: We consider the new divisor 200 and the new remainder 105, and apply the division lemma to get
200 = 105 x 1 + 95
We consider the new divisor 105 and the new remainder 95,and apply the division lemma to get
105 = 95 x 1 + 10
We consider the new divisor 95 and the new remainder 10,and apply the division lemma to get
95 = 10 x 9 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 905 and 705 is 5
Notice that 5 = HCF(10,5) = HCF(95,10) = HCF(105,95) = HCF(200,105) = HCF(705,200) = HCF(905,705) .
