HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 4019, 3663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 4019, 3663 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, 4019, 3663 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, 4019, 3663 is 1.
HCF(242, 4019, 3663) = 1
HCF of 242, 4019, 3663 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, 4019, 3663 is 1.
Highest Common Factor of 242,4019,3663 is 1
Step 1: Since 4019 > 242, we apply the division lemma to 4019 and 242, to get
4019 = 242 x 16 + 147
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 147 and 242, to get
242 = 147 x 1 + 95
Step 3: We consider the new divisor 147 and the new remainder 95, and apply the division lemma to get
147 = 95 x 1 + 52
We consider the new divisor 95 and the new remainder 52,and apply the division lemma to get
95 = 52 x 1 + 43
We consider the new divisor 52 and the new remainder 43,and apply the division lemma to get
52 = 43 x 1 + 9
We consider the new divisor 43 and the new remainder 9,and apply the division lemma to get
43 = 9 x 4 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 4019 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(43,9) = HCF(52,43) = HCF(95,52) = HCF(147,95) = HCF(242,147) = HCF(4019,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 3663 > 1, we apply the division lemma to 3663 and 1, to get
3663 = 1 x 3663 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3663 is 1
Notice that 1 = HCF(3663,1) .
