HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 130, 450, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 130, 450, 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 130, 450, 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 130, 450, 251 is 1.
HCF(130, 450, 251) = 1
HCF of 130, 450, 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 130, 450, 251 is 1.
Highest Common Factor of 130,450,251 is 1
Step 1: Since 450 > 130, we apply the division lemma to 450 and 130, to get
450 = 130 x 3 + 60
Step 2: Since the reminder 130 ≠ 0, we apply division lemma to 60 and 130, to get
130 = 60 x 2 + 10
Step 3: We consider the new divisor 60 and the new remainder 10, and apply the division lemma to get
60 = 10 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 130 and 450 is 10
Notice that 10 = HCF(60,10) = HCF(130,60) = HCF(450,130) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 251 > 10, we apply the division lemma to 251 and 10, to get
251 = 10 x 25 + 1
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 1 and 10, to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 251 is 1
Notice that 1 = HCF(10,1) = HCF(251,10) .
