HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 345, 799 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 345, 799 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 378, 345, 799 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 378, 345, 799 is 1.
HCF(378, 345, 799) = 1
HCF of 378, 345, 799 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 378, 345, 799 is 1.
Highest Common Factor of 378,345,799 is 1
Step 1: Since 378 > 345, we apply the division lemma to 378 and 345, to get
378 = 345 x 1 + 33
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 33 and 345, to get
345 = 33 x 10 + 15
Step 3: We consider the new divisor 33 and the new remainder 15, and apply the division lemma to get
33 = 15 x 2 + 3
We consider the new divisor 15 and the new remainder 3, and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 378 and 345 is 3
Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(345,33) = HCF(378,345) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 799 > 3, we apply the division lemma to 799 and 3, to get
799 = 3 x 266 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 799 is 1
Notice that 1 = HCF(3,1) = HCF(799,3) .
