HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 256, 979, 485, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 256, 979, 485, 86 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 256, 979, 485, 86 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 256, 979, 485, 86 is 1.
HCF(256, 979, 485, 86) = 1
HCF of 256, 979, 485, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 256, 979, 485, 86 is 1.
Highest Common Factor of 256,979,485,86 is 1
Step 1: Since 979 > 256, we apply the division lemma to 979 and 256, to get
979 = 256 x 3 + 211
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 211 and 256, to get
256 = 211 x 1 + 45
Step 3: We consider the new divisor 211 and the new remainder 45, and apply the division lemma to get
211 = 45 x 4 + 31
We consider the new divisor 45 and the new remainder 31,and apply the division lemma to get
45 = 31 x 1 + 14
We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get
31 = 14 x 2 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 256 and 979 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(45,31) = HCF(211,45) = HCF(256,211) = HCF(979,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 1, we apply the division lemma to 485 and 1, to get
485 = 1 x 485 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 485 is 1
Notice that 1 = HCF(485,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
