HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 18, 94, 38, 50 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 18, 94, 38, 50 is 2 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 18, 94, 38, 50 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 18, 94, 38, 50 is 2.
HCF(18, 94, 38, 50) = 2
HCF of 18, 94, 38, 50 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 18, 94, 38, 50 is 2.
Highest Common Factor of 18,94,38,50 is 2
Step 1: Since 94 > 18, we apply the division lemma to 94 and 18, to get
94 = 18 x 5 + 4
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 4 and 18, to get
18 = 4 x 4 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 18 and 94 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(94,18) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 2, we apply the division lemma to 38 and 2, to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 38 is 2
Notice that 2 = HCF(38,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 2, we apply the division lemma to 50 and 2, to get
50 = 2 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 50 is 2
Notice that 2 = HCF(50,2) .
