HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 105, 143, 898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 105, 143, 898 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 105, 143, 898 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 105, 143, 898 is 1.
HCF(105, 143, 898) = 1
HCF of 105, 143, 898 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 105, 143, 898 is 1.
Highest Common Factor of 105,143,898 is 1
Step 1: Since 143 > 105, we apply the division lemma to 143 and 105, to get
143 = 105 x 1 + 38
Step 2: Since the reminder 105 ≠ 0, we apply division lemma to 38 and 105, to get
105 = 38 x 2 + 29
Step 3: We consider the new divisor 38 and the new remainder 29, and apply the division lemma to get
38 = 29 x 1 + 9
We consider the new divisor 29 and the new remainder 9,and apply the division lemma to get
29 = 9 x 3 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 105 and 143 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(29,9) = HCF(38,29) = HCF(105,38) = HCF(143,105) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 898 > 1, we apply the division lemma to 898 and 1, to get
898 = 1 x 898 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 898 is 1
Notice that 1 = HCF(898,1) .
