HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3890, 7686, 72288 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 3890, 7686, 72288 is 2 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 3890, 7686, 72288 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 3890, 7686, 72288 is 2.
HCF(3890, 7686, 72288) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 3890, 7686, 72288 is 2.
Step 1: Since 7686 > 3890, we apply the division lemma to 7686 and 3890, to get
7686 = 3890 x 1 + 3796
Step 2: Since the reminder 3890 ≠ 0, we apply division lemma to 3796 and 3890, to get
3890 = 3796 x 1 + 94
Step 3: We consider the new divisor 3796 and the new remainder 94, and apply the division lemma to get
3796 = 94 x 40 + 36
We consider the new divisor 94 and the new remainder 36,and apply the division lemma to get
94 = 36 x 2 + 22
We consider the new divisor 36 and the new remainder 22,and apply the division lemma to get
36 = 22 x 1 + 14
We consider the new divisor 22 and the new remainder 14,and apply the division lemma to get
22 = 14 x 1 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 3890 and 7686 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(22,14) = HCF(36,22) = HCF(94,36) = HCF(3796,94) = HCF(3890,3796) = HCF(7686,3890) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72288 > 2, we apply the division lemma to 72288 and 2, to get
72288 = 2 x 36144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 72288 is 2
Notice that 2 = HCF(72288,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
