HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1787, 3789 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1787, 3789 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 1787, 3789 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 1787, 3789 is 1.
HCF(1787, 3789) = 1
HCF of 1787, 3789 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1787, 3789 is 1.
Highest Common Factor of 1787,3789 is 1
Step 1: Since 3789 > 1787, we apply the division lemma to 3789 and 1787, to get
3789 = 1787 x 2 + 215
Step 2: Since the reminder 1787 ≠ 0, we apply division lemma to 215 and 1787, to get
1787 = 215 x 8 + 67
Step 3: We consider the new divisor 215 and the new remainder 67, and apply the division lemma to get
215 = 67 x 3 + 14
We consider the new divisor 67 and the new remainder 14,and apply the division lemma to get
67 = 14 x 4 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 1787 and 3789 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(67,14) = HCF(215,67) = HCF(1787,215) = HCF(3789,1787) .
