HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 399, 298 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 253, 399, 298 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 253, 399, 298 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 253, 399, 298 is 1.
HCF(253, 399, 298) = 1
HCF of 253, 399, 298 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 253, 399, 298 is 1.
Highest Common Factor of 253,399,298 is 1
Step 1: Since 399 > 253, we apply the division lemma to 399 and 253, to get
399 = 253 x 1 + 146
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 146 and 253, to get
253 = 146 x 1 + 107
Step 3: We consider the new divisor 146 and the new remainder 107, and apply the division lemma to get
146 = 107 x 1 + 39
We consider the new divisor 107 and the new remainder 39,and apply the division lemma to get
107 = 39 x 2 + 29
We consider the new divisor 39 and the new remainder 29,and apply the division lemma to get
39 = 29 x 1 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 253 and 399 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(39,29) = HCF(107,39) = HCF(146,107) = HCF(253,146) = HCF(399,253) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 298 > 1, we apply the division lemma to 298 and 1, to get
298 = 1 x 298 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 298 is 1
Notice that 1 = HCF(298,1) .
