HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 32, 85, 439, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 32, 85, 439, 257 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 32, 85, 439, 257 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 32, 85, 439, 257 is 1.
HCF(32, 85, 439, 257) = 1
HCF of 32, 85, 439, 257 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 32, 85, 439, 257 is 1.
Highest Common Factor of 32,85,439,257 is 1
Step 1: Since 85 > 32, we apply the division lemma to 85 and 32, to get
85 = 32 x 2 + 21
Step 2: Since the reminder 32 ≠ 0, we apply division lemma to 21 and 32, to get
32 = 21 x 1 + 11
Step 3: We consider the new divisor 21 and the new remainder 11, and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma 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 32 and 85 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(32,21) = HCF(85,32) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 1, we apply the division lemma to 439 and 1, to get
439 = 1 x 439 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 439 is 1
Notice that 1 = HCF(439,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 257 > 1, we apply the division lemma to 257 and 1, to get
257 = 1 x 257 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 257 is 1
Notice that 1 = HCF(257,1) .
