HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 857, 444, 496 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 857, 444, 496 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 242, 857, 444, 496 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 242, 857, 444, 496 is 1.
HCF(242, 857, 444, 496) = 1
HCF of 242, 857, 444, 496 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 242, 857, 444, 496 is 1.
Highest Common Factor of 242,857,444,496 is 1
Step 1: Since 857 > 242, we apply the division lemma to 857 and 242, to get
857 = 242 x 3 + 131
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 131 and 242, to get
242 = 131 x 1 + 111
Step 3: We consider the new divisor 131 and the new remainder 111, and apply the division lemma to get
131 = 111 x 1 + 20
We consider the new divisor 111 and the new remainder 20,and apply the division lemma to get
111 = 20 x 5 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 242 and 857 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(111,20) = HCF(131,111) = HCF(242,131) = HCF(857,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 444 > 1, we apply the division lemma to 444 and 1, to get
444 = 1 x 444 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 444 is 1
Notice that 1 = HCF(444,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 496 > 1, we apply the division lemma to 496 and 1, to get
496 = 1 x 496 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 496 is 1
Notice that 1 = HCF(496,1) .
