HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 262, 987, 749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 262, 987, 749 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 262, 987, 749 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 262, 987, 749 is 1.
HCF(262, 987, 749) = 1
HCF of 262, 987, 749 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 262, 987, 749 is 1.
Highest Common Factor of 262,987,749 is 1
Step 1: Since 987 > 262, we apply the division lemma to 987 and 262, to get
987 = 262 x 3 + 201
Step 2: Since the reminder 262 ≠ 0, we apply division lemma to 201 and 262, to get
262 = 201 x 1 + 61
Step 3: We consider the new divisor 201 and the new remainder 61, and apply the division lemma to get
201 = 61 x 3 + 18
We consider the new divisor 61 and the new remainder 18,and apply the division lemma to get
61 = 18 x 3 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 262 and 987 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(61,18) = HCF(201,61) = HCF(262,201) = HCF(987,262) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 749 > 1, we apply the division lemma to 749 and 1, to get
749 = 1 x 749 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 749 is 1
Notice that 1 = HCF(749,1) .
