HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 749, 2449, 5777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 749, 2449, 5777 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 749, 2449, 5777 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 749, 2449, 5777 is 1.
HCF(749, 2449, 5777) = 1
HCF of 749, 2449, 5777 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 749, 2449, 5777 is 1.
Highest Common Factor of 749,2449,5777 is 1
Step 1: Since 2449 > 749, we apply the division lemma to 2449 and 749, to get
2449 = 749 x 3 + 202
Step 2: Since the reminder 749 ≠ 0, we apply division lemma to 202 and 749, to get
749 = 202 x 3 + 143
Step 3: We consider the new divisor 202 and the new remainder 143, and apply the division lemma to get
202 = 143 x 1 + 59
We consider the new divisor 143 and the new remainder 59,and apply the division lemma to get
143 = 59 x 2 + 25
We consider the new divisor 59 and the new remainder 25,and apply the division lemma to get
59 = 25 x 2 + 9
We consider the new divisor 25 and the new remainder 9,and apply the division lemma to get
25 = 9 x 2 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 749 and 2449 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(25,9) = HCF(59,25) = HCF(143,59) = HCF(202,143) = HCF(749,202) = HCF(2449,749) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5777 > 1, we apply the division lemma to 5777 and 1, to get
5777 = 1 x 5777 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 5777 is 1
Notice that 1 = HCF(5777,1) .
