HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 57, 76, 21, 313 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 57, 76, 21, 313 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 57, 76, 21, 313 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 57, 76, 21, 313 is 1.
HCF(57, 76, 21, 313) = 1
HCF of 57, 76, 21, 313 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 57, 76, 21, 313 is 1.
Highest Common Factor of 57,76,21,313 is 1
Step 1: Since 76 > 57, we apply the division lemma to 76 and 57, to get
76 = 57 x 1 + 19
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 19 and 57, to get
57 = 19 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 57 and 76 is 19
Notice that 19 = HCF(57,19) = HCF(76,57) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 19, we apply the division lemma to 21 and 19, to get
21 = 19 x 1 + 2
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 2 and 19, to get
19 = 2 x 9 + 1
Step 3: 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 19 and 21 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 313 > 1, we apply the division lemma to 313 and 1, to get
313 = 1 x 313 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 313 is 1
Notice that 1 = HCF(313,1) .
