HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 160, 250, 342, 27 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 160, 250, 342, 27 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 160, 250, 342, 27 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 160, 250, 342, 27 is 1.
HCF(160, 250, 342, 27) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 160, 250, 342, 27 is 1.
Step 1: Since 250 > 160, we apply the division lemma to 250 and 160, to get
250 = 160 x 1 + 90
Step 2: Since the reminder 160 ≠ 0, we apply division lemma to 90 and 160, to get
160 = 90 x 1 + 70
Step 3: We consider the new divisor 90 and the new remainder 70, and apply the division lemma to get
90 = 70 x 1 + 20
We consider the new divisor 70 and the new remainder 20,and apply the division lemma to get
70 = 20 x 3 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 160 and 250 is 10
Notice that 10 = HCF(20,10) = HCF(70,20) = HCF(90,70) = HCF(160,90) = HCF(250,160) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 342 > 10, we apply the division lemma to 342 and 10, to get
342 = 10 x 34 + 2
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 2 and 10, to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 342 is 2
Notice that 2 = HCF(10,2) = HCF(342,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 27 > 2, we apply the division lemma to 27 and 2, to get
27 = 2 x 13 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 27 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 160, 250, 342, 27?
Answer: HCF of 160, 250, 342, 27 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 160, 250, 342, 27 using Euclid's Algorithm?
