HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 244, 456, 42, 666 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 244, 456, 42, 666 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 244, 456, 42, 666 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 244, 456, 42, 666 is 2.
HCF(244, 456, 42, 666) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 244, 456, 42, 666 is 2.
Step 1: Since 456 > 244, we apply the division lemma to 456 and 244, to get
456 = 244 x 1 + 212
Step 2: Since the reminder 244 ≠ 0, we apply division lemma to 212 and 244, to get
244 = 212 x 1 + 32
Step 3: We consider the new divisor 212 and the new remainder 32, and apply the division lemma to get
212 = 32 x 6 + 20
We consider the new divisor 32 and the new remainder 20,and apply the division lemma to get
32 = 20 x 1 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 244 and 456 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(212,32) = HCF(244,212) = HCF(456,244) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 4, we apply the division lemma to 42 and 4, to get
42 = 4 x 10 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 42 is 2
Notice that 2 = HCF(4,2) = HCF(42,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 666 > 2, we apply the division lemma to 666 and 2, to get
666 = 2 x 333 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 666 is 2
Notice that 2 = HCF(666,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
