HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 42, 48, 80, 46 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 42, 48, 80, 46 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 42, 48, 80, 46 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 42, 48, 80, 46 is 2.
HCF(42, 48, 80, 46) = 2
HCF of 42, 48, 80, 46 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 42, 48, 80, 46 is 2.
Highest Common Factor of 42,48,80,46 is 2
Step 1: Since 48 > 42, we apply the division lemma to 48 and 42, to get
48 = 42 x 1 + 6
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 6 and 42, to get
42 = 6 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 42 and 48 is 6
Notice that 6 = HCF(42,6) = HCF(48,42) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 6, we apply the division lemma to 80 and 6, to get
80 = 6 x 13 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, 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 6 and 80 is 2
Notice that 2 = HCF(6,2) = HCF(80,6) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 46 > 2, we apply the division lemma to 46 and 2, to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 46 is 2
Notice that 2 = HCF(46,2) .
