HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 616, 444, 103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 616, 444, 103 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 616, 444, 103 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 616, 444, 103 is 1.
HCF(616, 444, 103) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 616, 444, 103 is 1.
Step 1: Since 616 > 444, we apply the division lemma to 616 and 444, to get
616 = 444 x 1 + 172
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 172 and 444, to get
444 = 172 x 2 + 100
Step 3: We consider the new divisor 172 and the new remainder 100, and apply the division lemma to get
172 = 100 x 1 + 72
We consider the new divisor 100 and the new remainder 72,and apply the division lemma to get
100 = 72 x 1 + 28
We consider the new divisor 72 and the new remainder 28,and apply the division lemma to get
72 = 28 x 2 + 16
We consider the new divisor 28 and the new remainder 16,and apply the division lemma to get
28 = 16 x 1 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 616 and 444 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(72,28) = HCF(100,72) = HCF(172,100) = HCF(444,172) = HCF(616,444) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 103 > 4, we apply the division lemma to 103 and 4, to get
103 = 4 x 25 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 103 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(103,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
