HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 1906 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 1906 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 605, 1906 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 605, 1906 is 1.
HCF(605, 1906) = 1
HCF of 605, 1906 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 1906 is 1.
Highest Common Factor of 605,1906 is 1
Step 1: Since 1906 > 605, we apply the division lemma to 1906 and 605, to get
1906 = 605 x 3 + 91
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 91 and 605, to get
605 = 91 x 6 + 59
Step 3: We consider the new divisor 91 and the new remainder 59, and apply the division lemma to get
91 = 59 x 1 + 32
We consider the new divisor 59 and the new remainder 32,and apply the division lemma to get
59 = 32 x 1 + 27
We consider the new divisor 32 and the new remainder 27,and apply the division lemma to get
32 = 27 x 1 + 5
We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get
27 = 5 x 5 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 605 and 1906 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(32,27) = HCF(59,32) = HCF(91,59) = HCF(605,91) = HCF(1906,605) .
