HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 5603, 1108 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 5603, 1108 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 390, 5603, 1108 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 390, 5603, 1108 is 1.
HCF(390, 5603, 1108) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 5603, 1108 is 1.
Step 1: Since 5603 > 390, we apply the division lemma to 5603 and 390, to get
5603 = 390 x 14 + 143
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 143 and 390, to get
390 = 143 x 2 + 104
Step 3: We consider the new divisor 143 and the new remainder 104, and apply the division lemma to get
143 = 104 x 1 + 39
We consider the new divisor 104 and the new remainder 39,and apply the division lemma to get
104 = 39 x 2 + 26
We consider the new divisor 39 and the new remainder 26,and apply the division lemma to get
39 = 26 x 1 + 13
We consider the new divisor 26 and the new remainder 13,and apply the division lemma to get
26 = 13 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 390 and 5603 is 13
Notice that 13 = HCF(26,13) = HCF(39,26) = HCF(104,39) = HCF(143,104) = HCF(390,143) = HCF(5603,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1108 > 13, we apply the division lemma to 1108 and 13, to get
1108 = 13 x 85 + 3
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 3 and 13, to get
13 = 3 x 4 + 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 13 and 1108 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(1108,13) .
Here are some samples of HCF using Euclid's Algorithm calculations.
