HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 452, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 251, 452, 917 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 251, 452, 917 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 251, 452, 917 is 1.
HCF(251, 452, 917) = 1
HCF of 251, 452, 917 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 251, 452, 917 is 1.
Highest Common Factor of 251,452,917 is 1
Step 1: Since 452 > 251, we apply the division lemma to 452 and 251, to get
452 = 251 x 1 + 201
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 201 and 251, to get
251 = 201 x 1 + 50
Step 3: We consider the new divisor 201 and the new remainder 50, and apply the division lemma to get
201 = 50 x 4 + 1
We consider the new divisor 50 and the new remainder 1, and apply the division lemma to get
50 = 1 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 452 is 1
Notice that 1 = HCF(50,1) = HCF(201,50) = HCF(251,201) = HCF(452,251) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 917 > 1, we apply the division lemma to 917 and 1, to get
917 = 1 x 917 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 917 is 1
Notice that 1 = HCF(917,1) .
