HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 444, 605, 425, 289 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 444, 605, 425, 289 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 444, 605, 425, 289 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 444, 605, 425, 289 is 1.
HCF(444, 605, 425, 289) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 444, 605, 425, 289 is 1.
Step 1: Since 605 > 444, we apply the division lemma to 605 and 444, to get
605 = 444 x 1 + 161
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 161 and 444, to get
444 = 161 x 2 + 122
Step 3: We consider the new divisor 161 and the new remainder 122, and apply the division lemma to get
161 = 122 x 1 + 39
We consider the new divisor 122 and the new remainder 39,and apply the division lemma to get
122 = 39 x 3 + 5
We consider the new divisor 39 and the new remainder 5,and apply the division lemma to get
39 = 5 x 7 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 444 and 605 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(39,5) = HCF(122,39) = HCF(161,122) = HCF(444,161) = HCF(605,444) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 1, we apply the division lemma to 425 and 1, to get
425 = 1 x 425 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 425 is 1
Notice that 1 = HCF(425,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 289 > 1, we apply the division lemma to 289 and 1, to get
289 = 1 x 289 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 289 is 1
Notice that 1 = HCF(289,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
