HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 517 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 381, 517 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 381, 517 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 381, 517 is 1.
HCF(381, 517) = 1
HCF of 381, 517 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 381, 517 is 1.
Highest Common Factor of 381,517 is 1
Step 1: Since 517 > 381, we apply the division lemma to 517 and 381, to get
517 = 381 x 1 + 136
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 136 and 381, to get
381 = 136 x 2 + 109
Step 3: We consider the new divisor 136 and the new remainder 109, and apply the division lemma to get
136 = 109 x 1 + 27
We consider the new divisor 109 and the new remainder 27,and apply the division lemma to get
109 = 27 x 4 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 517 is 1
Notice that 1 = HCF(27,1) = HCF(109,27) = HCF(136,109) = HCF(381,136) = HCF(517,381) .
