HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 3820 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 387, 3820 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 387, 3820 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 387, 3820 is 1.
HCF(387, 3820) = 1
HCF of 387, 3820 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 387, 3820 is 1.
Highest Common Factor of 387,3820 is 1
Step 1: Since 3820 > 387, we apply the division lemma to 3820 and 387, to get
3820 = 387 x 9 + 337
Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 337 and 387, to get
387 = 337 x 1 + 50
Step 3: We consider the new divisor 337 and the new remainder 50, and apply the division lemma to get
337 = 50 x 6 + 37
We consider the new divisor 50 and the new remainder 37,and apply the division lemma to get
50 = 37 x 1 + 13
We consider the new divisor 37 and the new remainder 13,and apply the division lemma to get
37 = 13 x 2 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 387 and 3820 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(37,13) = HCF(50,37) = HCF(337,50) = HCF(387,337) = HCF(3820,387) .
