HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 449, 891, 53 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 449, 891, 53 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 126, 449, 891, 53 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 126, 449, 891, 53 is 1.
HCF(126, 449, 891, 53) = 1
HCF of 126, 449, 891, 53 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 126, 449, 891, 53 is 1.
Highest Common Factor of 126,449,891,53 is 1
Step 1: Since 449 > 126, we apply the division lemma to 449 and 126, to get
449 = 126 x 3 + 71
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 71 and 126, to get
126 = 71 x 1 + 55
Step 3: We consider the new divisor 71 and the new remainder 55, and apply the division lemma to get
71 = 55 x 1 + 16
We consider the new divisor 55 and the new remainder 16,and apply the division lemma to get
55 = 16 x 3 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 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 126 and 449 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(55,16) = HCF(71,55) = HCF(126,71) = HCF(449,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 1, we apply the division lemma to 891 and 1, to get
891 = 1 x 891 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 891 is 1
Notice that 1 = HCF(891,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 1, we apply the division lemma to 53 and 1, to get
53 = 1 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 53 is 1
Notice that 1 = HCF(53,1) .
