HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 649, 508 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 449, 649, 508 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 449, 649, 508 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 449, 649, 508 is 1.
HCF(449, 649, 508) = 1
HCF of 449, 649, 508 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 449, 649, 508 is 1.
Highest Common Factor of 449,649,508 is 1
Step 1: Since 649 > 449, we apply the division lemma to 649 and 449, to get
649 = 449 x 1 + 200
Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 200 and 449, to get
449 = 200 x 2 + 49
Step 3: We consider the new divisor 200 and the new remainder 49, and apply the division lemma to get
200 = 49 x 4 + 4
We consider the new divisor 49 and the new remainder 4,and apply the division lemma to get
49 = 4 x 12 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 449 and 649 is 1
Notice that 1 = HCF(4,1) = HCF(49,4) = HCF(200,49) = HCF(449,200) = HCF(649,449) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 508 > 1, we apply the division lemma to 508 and 1, to get
508 = 1 x 508 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 508 is 1
Notice that 1 = HCF(508,1) .
