HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 265, 106, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 265, 106, 18 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 605, 265, 106, 18 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 605, 265, 106, 18 is 1.
HCF(605, 265, 106, 18) = 1
HCF of 605, 265, 106, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 265, 106, 18 is 1.
Highest Common Factor of 605,265,106,18 is 1
Step 1: Since 605 > 265, we apply the division lemma to 605 and 265, to get
605 = 265 x 2 + 75
Step 2: Since the reminder 265 ≠ 0, we apply division lemma to 75 and 265, to get
265 = 75 x 3 + 40
Step 3: We consider the new divisor 75 and the new remainder 40, and apply the division lemma to get
75 = 40 x 1 + 35
We consider the new divisor 40 and the new remainder 35,and apply the division lemma to get
40 = 35 x 1 + 5
We consider the new divisor 35 and the new remainder 5,and apply the division lemma to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 605 and 265 is 5
Notice that 5 = HCF(35,5) = HCF(40,35) = HCF(75,40) = HCF(265,75) = HCF(605,265) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 106 > 5, we apply the division lemma to 106 and 5, to get
106 = 5 x 21 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 106 is 1
Notice that 1 = HCF(5,1) = HCF(106,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1
Notice that 1 = HCF(18,1) .
