HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 898, 450, 634 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 898, 450, 634 is 2 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 898, 450, 634 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 898, 450, 634 is 2.
HCF(898, 450, 634) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 898, 450, 634 is 2.
Step 1: Since 898 > 450, we apply the division lemma to 898 and 450, to get
898 = 450 x 1 + 448
Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 448 and 450, to get
450 = 448 x 1 + 2
Step 3: We consider the new divisor 448 and the new remainder 2, and apply the division lemma to get
448 = 2 x 224 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 898 and 450 is 2
Notice that 2 = HCF(448,2) = HCF(450,448) = HCF(898,450) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 634 > 2, we apply the division lemma to 634 and 2, to get
634 = 2 x 317 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 634 is 2
Notice that 2 = HCF(634,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
