HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2787, 3924 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 2787, 3924 is 3 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 2787, 3924 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 2787, 3924 is 3.
HCF(2787, 3924) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2787, 3924 is 3.
Step 1: Since 3924 > 2787, we apply the division lemma to 3924 and 2787, to get
3924 = 2787 x 1 + 1137
Step 2: Since the reminder 2787 ≠ 0, we apply division lemma to 1137 and 2787, to get
2787 = 1137 x 2 + 513
Step 3: We consider the new divisor 1137 and the new remainder 513, and apply the division lemma to get
1137 = 513 x 2 + 111
We consider the new divisor 513 and the new remainder 111,and apply the division lemma to get
513 = 111 x 4 + 69
We consider the new divisor 111 and the new remainder 69,and apply the division lemma to get
111 = 69 x 1 + 42
We consider the new divisor 69 and the new remainder 42,and apply the division lemma to get
69 = 42 x 1 + 27
We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get
42 = 27 x 1 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 2787 and 3924 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(69,42) = HCF(111,69) = HCF(513,111) = HCF(1137,513) = HCF(2787,1137) = HCF(3924,2787) .
Here are some samples of HCF using Euclid's Algorithm calculations.
