HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 469, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 469, 64 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 432, 469, 64 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 432, 469, 64 is 1.
HCF(432, 469, 64) = 1
HCF of 432, 469, 64 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 469, 64 is 1.
Highest Common Factor of 432,469,64 is 1
Step 1: Since 469 > 432, we apply the division lemma to 469 and 432, to get
469 = 432 x 1 + 37
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 37 and 432, to get
432 = 37 x 11 + 25
Step 3: We consider the new divisor 37 and the new remainder 25, and apply the division lemma to get
37 = 25 x 1 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 432 and 469 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(37,25) = HCF(432,37) = HCF(469,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get
64 = 1 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1
Notice that 1 = HCF(64,1) .
