HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 68995 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 406, 68995 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 406, 68995 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 406, 68995 is 1.
HCF(406, 68995) = 1
HCF of 406, 68995 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 406, 68995 is 1.
Highest Common Factor of 406,68995 is 1
Step 1: Since 68995 > 406, we apply the division lemma to 68995 and 406, to get
68995 = 406 x 169 + 381
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 381 and 406, to get
406 = 381 x 1 + 25
Step 3: We consider the new divisor 381 and the new remainder 25, and apply the division lemma to get
381 = 25 x 15 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 406 and 68995 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(381,25) = HCF(406,381) = HCF(68995,406) .
