HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 164, 455, 565, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 164, 455, 565, 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 164, 455, 565, 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 164, 455, 565, 18 is 1.
HCF(164, 455, 565, 18) = 1
HCF of 164, 455, 565, 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 164, 455, 565, 18 is 1.
Highest Common Factor of 164,455,565,18 is 1
Step 1: Since 455 > 164, we apply the division lemma to 455 and 164, to get
455 = 164 x 2 + 127
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 127 and 164, to get
164 = 127 x 1 + 37
Step 3: We consider the new divisor 127 and the new remainder 37, and apply the division lemma to get
127 = 37 x 3 + 16
We consider the new divisor 37 and the new remainder 16,and apply the division lemma to get
37 = 16 x 2 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma 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 164 and 455 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(37,16) = HCF(127,37) = HCF(164,127) = HCF(455,164) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 565 > 1, we apply the division lemma to 565 and 1, to get
565 = 1 x 565 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 565 is 1
Notice that 1 = HCF(565,1) .
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) .
