HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 58, 88, 20, 146 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 58, 88, 20, 146 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 58, 88, 20, 146 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 58, 88, 20, 146 is 2.
HCF(58, 88, 20, 146) = 2
HCF of 58, 88, 20, 146 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 58, 88, 20, 146 is 2.
Highest Common Factor of 58,88,20,146 is 2
Step 1: Since 88 > 58, we apply the division lemma to 88 and 58, to get
88 = 58 x 1 + 30
Step 2: Since the reminder 58 ≠ 0, we apply division lemma to 30 and 58, to get
58 = 30 x 1 + 28
Step 3: We consider the new divisor 30 and the new remainder 28, and apply the division lemma to get
30 = 28 x 1 + 2
We consider the new divisor 28 and the new remainder 2, and apply the division lemma to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 58 and 88 is 2
Notice that 2 = HCF(28,2) = HCF(30,28) = HCF(58,30) = HCF(88,58) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 2, we apply the division lemma to 20 and 2, to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 20 is 2
Notice that 2 = HCF(20,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 146 > 2, we apply the division lemma to 146 and 2, to get
146 = 2 x 73 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 146 is 2
Notice that 2 = HCF(146,2) .
