HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 474, 869, 832 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 474, 869, 832 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 474, 869, 832 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 474, 869, 832 is 1.
HCF(474, 869, 832) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 474, 869, 832 is 1.
Step 1: Since 869 > 474, we apply the division lemma to 869 and 474, to get
869 = 474 x 1 + 395
Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 395 and 474, to get
474 = 395 x 1 + 79
Step 3: We consider the new divisor 395 and the new remainder 79, and apply the division lemma to get
395 = 79 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 79, the HCF of 474 and 869 is 79
Notice that 79 = HCF(395,79) = HCF(474,395) = HCF(869,474) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 832 > 79, we apply the division lemma to 832 and 79, to get
832 = 79 x 10 + 42
Step 2: Since the reminder 79 ≠ 0, we apply division lemma to 42 and 79, to get
79 = 42 x 1 + 37
Step 3: We consider the new divisor 42 and the new remainder 37, and apply the division lemma to get
42 = 37 x 1 + 5
We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get
37 = 5 x 7 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 79 and 832 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(42,37) = HCF(79,42) = HCF(832,79) .
Here are some samples of HCF using Euclid's Algorithm calculations.
