HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 817 i.e. 19 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 817 is 19 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 380, 817 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 380, 817 is 19.
HCF(380, 817) = 19
HCF of 380, 817 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 817 is 19.
Highest Common Factor of 380,817 is 19
Step 1: Since 817 > 380, we apply the division lemma to 817 and 380, to get
817 = 380 x 2 + 57
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 57 and 380, to get
380 = 57 x 6 + 38
Step 3: We consider the new divisor 57 and the new remainder 38, and apply the division lemma to get
57 = 38 x 1 + 19
We consider the new divisor 38 and the new remainder 19, and apply the division lemma to get
38 = 19 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 380 and 817 is 19
Notice that 19 = HCF(38,19) = HCF(57,38) = HCF(380,57) = HCF(817,380) .
