HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 50, 20, 88, 115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 50, 20, 88, 115 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 50, 20, 88, 115 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 50, 20, 88, 115 is 1.
HCF(50, 20, 88, 115) = 1
HCF of 50, 20, 88, 115 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 50, 20, 88, 115 is 1.
Highest Common Factor of 50,20,88,115 is 1
Step 1: Since 50 > 20, we apply the division lemma to 50 and 20, to get
50 = 20 x 2 + 10
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 10 and 20, 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 50 and 20 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 88 > 10, we apply the division lemma to 88 and 10, to get
88 = 10 x 8 + 8
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get
10 = 8 x 1 + 2
Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 88 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(88,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 115 > 2, we apply the division lemma to 115 and 2, to get
115 = 2 x 57 + 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 115 is 1
Notice that 1 = HCF(2,1) = HCF(115,2) .
