HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 82, 48, 87, 90 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 82, 48, 87, 90 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 82, 48, 87, 90 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 82, 48, 87, 90 is 1.
HCF(82, 48, 87, 90) = 1
HCF of 82, 48, 87, 90 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 82, 48, 87, 90 is 1.
Highest Common Factor of 82,48,87,90 is 1
Step 1: Since 82 > 48, we apply the division lemma to 82 and 48, to get
82 = 48 x 1 + 34
Step 2: Since the reminder 48 ≠ 0, we apply division lemma to 34 and 48, to get
48 = 34 x 1 + 14
Step 3: We consider the new divisor 34 and the new remainder 14, and apply the division lemma to get
34 = 14 x 2 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 82 and 48 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(48,34) = HCF(82,48) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 2, we apply the division lemma to 87 and 2, to get
87 = 2 x 43 + 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 87 is 1
Notice that 1 = HCF(2,1) = HCF(87,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 1, we apply the division lemma to 90 and 1, to get
90 = 1 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90 is 1
Notice that 1 = HCF(90,1) .
