HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 7381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 7381 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, 7381 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, 7381 is 1.
HCF(705, 7381) = 1
HCF of 705, 7381 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, 7381 is 1.
Highest Common Factor of 705,7381 is 1
Step 1: Since 7381 > 705, we apply the division lemma to 7381 and 705, to get
7381 = 705 x 10 + 331
Step 2: Since the reminder 705 ≠ 0, we apply division lemma to 331 and 705, to get
705 = 331 x 2 + 43
Step 3: We consider the new divisor 331 and the new remainder 43, and apply the division lemma to get
331 = 43 x 7 + 30
We consider the new divisor 43 and the new remainder 30,and apply the division lemma to get
43 = 30 x 1 + 13
We consider the new divisor 30 and the new remainder 13,and apply the division lemma to get
30 = 13 x 2 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 705 and 7381 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(43,30) = HCF(331,43) = HCF(705,331) = HCF(7381,705) .
