HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 82, 58, 100 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 82, 58, 100 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 68, 82, 58, 100 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 68, 82, 58, 100 is 2.
HCF(68, 82, 58, 100) = 2
HCF of 68, 82, 58, 100 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 82, 58, 100 is 2.
Highest Common Factor of 68,82,58,100 is 2
Step 1: Since 82 > 68, we apply the division lemma to 82 and 68, to get
82 = 68 x 1 + 14
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 14 and 68, to get
68 = 14 x 4 + 12
Step 3: We consider the new divisor 14 and the new remainder 12, and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2, and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 68 and 82 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(68,14) = HCF(82,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 58 > 2, we apply the division lemma to 58 and 2, to get
58 = 2 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 58 is 2
Notice that 2 = HCF(58,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 2, we apply the division lemma to 100 and 2, to get
100 = 2 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 100 is 2
Notice that 2 = HCF(100,2) .
