HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 351, 538 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 351, 538 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 825, 351, 538 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 825, 351, 538 is 1.
HCF(825, 351, 538) = 1
HCF of 825, 351, 538 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 351, 538 is 1.
Highest Common Factor of 825,351,538 is 1
Step 1: Since 825 > 351, we apply the division lemma to 825 and 351, to get
825 = 351 x 2 + 123
Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 123 and 351, to get
351 = 123 x 2 + 105
Step 3: We consider the new divisor 123 and the new remainder 105, and apply the division lemma to get
123 = 105 x 1 + 18
We consider the new divisor 105 and the new remainder 18,and apply the division lemma to get
105 = 18 x 5 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 825 and 351 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(105,18) = HCF(123,105) = HCF(351,123) = HCF(825,351) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 538 > 3, we apply the division lemma to 538 and 3, to get
538 = 3 x 179 + 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 538 is 1
Notice that 1 = HCF(3,1) = HCF(538,3) .
