HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 5787, 3052 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 5787, 3052 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 395, 5787, 3052 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 395, 5787, 3052 is 1.
HCF(395, 5787, 3052) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 395, 5787, 3052 is 1.
Step 1: Since 5787 > 395, we apply the division lemma to 5787 and 395, to get
5787 = 395 x 14 + 257
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 257 and 395, to get
395 = 257 x 1 + 138
Step 3: We consider the new divisor 257 and the new remainder 138, and apply the division lemma to get
257 = 138 x 1 + 119
We consider the new divisor 138 and the new remainder 119,and apply the division lemma to get
138 = 119 x 1 + 19
We consider the new divisor 119 and the new remainder 19,and apply the division lemma to get
119 = 19 x 6 + 5
We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get
19 = 5 x 3 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 395 and 5787 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(119,19) = HCF(138,119) = HCF(257,138) = HCF(395,257) = HCF(5787,395) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 3052 > 1, we apply the division lemma to 3052 and 1, to get
3052 = 1 x 3052 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3052 is 1
Notice that 1 = HCF(3052,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
