HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 697, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 338, 697, 251 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 338, 697, 251 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 338, 697, 251 is 1.
HCF(338, 697, 251) = 1
HCF of 338, 697, 251 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 338, 697, 251 is 1.
Highest Common Factor of 338,697,251 is 1
Step 1: Since 697 > 338, we apply the division lemma to 697 and 338, to get
697 = 338 x 2 + 21
Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 21 and 338, to get
338 = 21 x 16 + 2
Step 3: We consider the new divisor 21 and the new remainder 2, and apply the division lemma to get
21 = 2 x 10 + 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 338 and 697 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(338,21) = HCF(697,338) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 251 > 1, we apply the division lemma to 251 and 1, to get
251 = 1 x 251 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 251 is 1
Notice that 1 = HCF(251,1) .
