HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 289, 262, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 289, 262, 57 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 981, 289, 262, 57 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 981, 289, 262, 57 is 1.
HCF(981, 289, 262, 57) = 1
HCF of 981, 289, 262, 57 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 981, 289, 262, 57 is 1.
Highest Common Factor of 981,289,262,57 is 1
Step 1: Since 981 > 289, we apply the division lemma to 981 and 289, to get
981 = 289 x 3 + 114
Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 114 and 289, to get
289 = 114 x 2 + 61
Step 3: We consider the new divisor 114 and the new remainder 61, and apply the division lemma to get
114 = 61 x 1 + 53
We consider the new divisor 61 and the new remainder 53,and apply the division lemma to get
61 = 53 x 1 + 8
We consider the new divisor 53 and the new remainder 8,and apply the division lemma to get
53 = 8 x 6 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 981 and 289 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(53,8) = HCF(61,53) = HCF(114,61) = HCF(289,114) = HCF(981,289) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 262 > 1, we apply the division lemma to 262 and 1, to get
262 = 1 x 262 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 262 is 1
Notice that 1 = HCF(262,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1
Notice that 1 = HCF(57,1) .
