HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 86, 654, 256 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 86, 654, 256 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 86, 654, 256 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 86, 654, 256 is 2.
HCF(86, 654, 256) = 2
HCF of 86, 654, 256 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 86, 654, 256 is 2.
Highest Common Factor of 86,654,256 is 2
Step 1: Since 654 > 86, we apply the division lemma to 654 and 86, to get
654 = 86 x 7 + 52
Step 2: Since the reminder 86 ≠ 0, we apply division lemma to 52 and 86, to get
86 = 52 x 1 + 34
Step 3: We consider the new divisor 52 and the new remainder 34, and apply the division lemma to get
52 = 34 x 1 + 18
We consider the new divisor 34 and the new remainder 18,and apply the division lemma to get
34 = 18 x 1 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 86 and 654 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(34,18) = HCF(52,34) = HCF(86,52) = HCF(654,86) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 256 > 2, we apply the division lemma to 256 and 2, to get
256 = 2 x 128 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 256 is 2
Notice that 2 = HCF(256,2) .
