HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 899, 378, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 899, 378, 49 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 493, 899, 378, 49 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 493, 899, 378, 49 is 1.
HCF(493, 899, 378, 49) = 1
HCF of 493, 899, 378, 49 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 899, 378, 49 is 1.
Highest Common Factor of 493,899,378,49 is 1
Step 1: Since 899 > 493, we apply the division lemma to 899 and 493, to get
899 = 493 x 1 + 406
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 406 and 493, to get
493 = 406 x 1 + 87
Step 3: We consider the new divisor 406 and the new remainder 87, and apply the division lemma to get
406 = 87 x 4 + 58
We consider the new divisor 87 and the new remainder 58,and apply the division lemma to get
87 = 58 x 1 + 29
We consider the new divisor 58 and the new remainder 29,and apply the division lemma to get
58 = 29 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 493 and 899 is 29
Notice that 29 = HCF(58,29) = HCF(87,58) = HCF(406,87) = HCF(493,406) = HCF(899,493) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 378 > 29, we apply the division lemma to 378 and 29, to get
378 = 29 x 13 + 1
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 1 and 29, to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 29 and 378 is 1
Notice that 1 = HCF(29,1) = HCF(378,29) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 1, we apply the division lemma to 49 and 1, to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 49 is 1
Notice that 1 = HCF(49,1) .
