HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 5797, 7243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 455, 5797, 7243 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 455, 5797, 7243 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 455, 5797, 7243 is 1.
HCF(455, 5797, 7243) = 1
HCF of 455, 5797, 7243 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 455, 5797, 7243 is 1.
Highest Common Factor of 455,5797,7243 is 1
Step 1: Since 5797 > 455, we apply the division lemma to 5797 and 455, to get
5797 = 455 x 12 + 337
Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 337 and 455, to get
455 = 337 x 1 + 118
Step 3: We consider the new divisor 337 and the new remainder 118, and apply the division lemma to get
337 = 118 x 2 + 101
We consider the new divisor 118 and the new remainder 101,and apply the division lemma to get
118 = 101 x 1 + 17
We consider the new divisor 101 and the new remainder 17,and apply the division lemma to get
101 = 17 x 5 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 455 and 5797 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(101,17) = HCF(118,101) = HCF(337,118) = HCF(455,337) = HCF(5797,455) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7243 > 1, we apply the division lemma to 7243 and 1, to get
7243 = 1 x 7243 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7243 is 1
Notice that 1 = HCF(7243,1) .
