HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 743 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 905, 743 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, 743 is 1.
HCF(905, 743) = 1
HCF of 905, 743 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, 743 is 1.
Highest Common Factor of 905,743 is 1
Step 1: Since 905 > 743, we apply the division lemma to 905 and 743, to get
905 = 743 x 1 + 162
Step 2: Since the reminder 743 ≠ 0, we apply division lemma to 162 and 743, to get
743 = 162 x 4 + 95
Step 3: We consider the new divisor 162 and the new remainder 95, and apply the division lemma to get
162 = 95 x 1 + 67
We consider the new divisor 95 and the new remainder 67,and apply the division lemma to get
95 = 67 x 1 + 28
We consider the new divisor 67 and the new remainder 28,and apply the division lemma to get
67 = 28 x 2 + 11
We consider the new divisor 28 and the new remainder 11,and apply the division lemma to get
28 = 11 x 2 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 905 and 743 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(67,28) = HCF(95,67) = HCF(162,95) = HCF(743,162) = HCF(905,743) .
