HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 483, 834, 97, 103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 483, 834, 97, 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 483, 834, 97, 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 483, 834, 97, 103 is 1.
HCF(483, 834, 97, 103) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 483, 834, 97, 103 is 1.
Step 1: Since 834 > 483, we apply the division lemma to 834 and 483, to get
834 = 483 x 1 + 351
Step 2: Since the reminder 483 ≠ 0, we apply division lemma to 351 and 483, to get
483 = 351 x 1 + 132
Step 3: We consider the new divisor 351 and the new remainder 132, and apply the division lemma to get
351 = 132 x 2 + 87
We consider the new divisor 132 and the new remainder 87,and apply the division lemma to get
132 = 87 x 1 + 45
We consider the new divisor 87 and the new remainder 45,and apply the division lemma to get
87 = 45 x 1 + 42
We consider the new divisor 45 and the new remainder 42,and apply the division lemma to get
45 = 42 x 1 + 3
We consider the new divisor 42 and the new remainder 3,and apply the division lemma to get
42 = 3 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 483 and 834 is 3
Notice that 3 = HCF(42,3) = HCF(45,42) = HCF(87,45) = HCF(132,87) = HCF(351,132) = HCF(483,351) = HCF(834,483) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 97 > 3, we apply the division lemma to 97 and 3, to get
97 = 3 x 32 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 97 is 1
Notice that 1 = HCF(3,1) = HCF(97,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 103 > 1, we apply the division lemma to 103 and 1, to get
103 = 1 x 103 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 103 is 1
Notice that 1 = HCF(103,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
