HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 64, 32, 10, 261 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 64, 32, 10, 261 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 64, 32, 10, 261 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 64, 32, 10, 261 is 1.
HCF(64, 32, 10, 261) = 1
HCF of 64, 32, 10, 261 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 64, 32, 10, 261 is 1.
Highest Common Factor of 64,32,10,261 is 1
Step 1: Since 64 > 32, we apply the division lemma to 64 and 32, to get
64 = 32 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 32, the HCF of 64 and 32 is 32
Notice that 32 = HCF(64,32) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 32 > 10, we apply the division lemma to 32 and 10, to get
32 = 10 x 3 + 2
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 2 and 10, to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 32 and 10 is 2
Notice that 2 = HCF(10,2) = HCF(32,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 261 > 2, we apply the division lemma to 261 and 2, to get
261 = 2 x 130 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 261 is 1
Notice that 1 = HCF(2,1) = HCF(261,2) .
