HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 190, 142, 381, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 190, 142, 381, 279 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 190, 142, 381, 279 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 190, 142, 381, 279 is 1.
HCF(190, 142, 381, 279) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 190, 142, 381, 279 is 1.
Step 1: Since 190 > 142, we apply the division lemma to 190 and 142, to get
190 = 142 x 1 + 48
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 48 and 142, to get
142 = 48 x 2 + 46
Step 3: We consider the new divisor 48 and the new remainder 46, and apply the division lemma to get
48 = 46 x 1 + 2
We consider the new divisor 46 and the new remainder 2, and apply the division lemma to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 190 and 142 is 2
Notice that 2 = HCF(46,2) = HCF(48,46) = HCF(142,48) = HCF(190,142) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 381 > 2, we apply the division lemma to 381 and 2, to get
381 = 2 x 190 + 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 381 is 1
Notice that 1 = HCF(2,1) = HCF(381,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 1, we apply the division lemma to 279 and 1, to get
279 = 1 x 279 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 279 is 1
Notice that 1 = HCF(279,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 190, 142, 381, 279?
Answer: HCF of 190, 142, 381, 279 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 190, 142, 381, 279 using Euclid's Algorithm?
