HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 612, 314, 716, 40 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 612, 314, 716, 40 is 2 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 612, 314, 716, 40 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 612, 314, 716, 40 is 2.
HCF(612, 314, 716, 40) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 612, 314, 716, 40 is 2.
Step 1: Since 612 > 314, we apply the division lemma to 612 and 314, to get
612 = 314 x 1 + 298
Step 2: Since the reminder 314 ≠ 0, we apply division lemma to 298 and 314, to get
314 = 298 x 1 + 16
Step 3: We consider the new divisor 298 and the new remainder 16, and apply the division lemma to get
298 = 16 x 18 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 612 and 314 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(298,16) = HCF(314,298) = HCF(612,314) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 716 > 2, we apply the division lemma to 716 and 2, to get
716 = 2 x 358 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 716 is 2
Notice that 2 = HCF(716,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 2, we apply the division lemma to 40 and 2, to get
40 = 2 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 40 is 2
Notice that 2 = HCF(40,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
