HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 2803, 1103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 2803, 1103 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 380, 2803, 1103 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 380, 2803, 1103 is 1.
HCF(380, 2803, 1103) = 1
HCF of 380, 2803, 1103 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 2803, 1103 is 1.
Highest Common Factor of 380,2803,1103 is 1
Step 1: Since 2803 > 380, we apply the division lemma to 2803 and 380, to get
2803 = 380 x 7 + 143
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 143 and 380, to get
380 = 143 x 2 + 94
Step 3: We consider the new divisor 143 and the new remainder 94, and apply the division lemma to get
143 = 94 x 1 + 49
We consider the new divisor 94 and the new remainder 49,and apply the division lemma to get
94 = 49 x 1 + 45
We consider the new divisor 49 and the new remainder 45,and apply the division lemma to get
49 = 45 x 1 + 4
We consider the new divisor 45 and the new remainder 4,and apply the division lemma to get
45 = 4 x 11 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 380 and 2803 is 1
Notice that 1 = HCF(4,1) = HCF(45,4) = HCF(49,45) = HCF(94,49) = HCF(143,94) = HCF(380,143) = HCF(2803,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1103 > 1, we apply the division lemma to 1103 and 1, to get
1103 = 1 x 1103 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1103 is 1
Notice that 1 = HCF(1103,1) .
