HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 846, 464, 940, 58 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 846, 464, 940, 58 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 846, 464, 940, 58 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 846, 464, 940, 58 is 2.
HCF(846, 464, 940, 58) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 846, 464, 940, 58 is 2.
Step 1: Since 846 > 464, we apply the division lemma to 846 and 464, to get
846 = 464 x 1 + 382
Step 2: Since the reminder 464 ≠ 0, we apply division lemma to 382 and 464, to get
464 = 382 x 1 + 82
Step 3: We consider the new divisor 382 and the new remainder 82, and apply the division lemma to get
382 = 82 x 4 + 54
We consider the new divisor 82 and the new remainder 54,and apply the division lemma to get
82 = 54 x 1 + 28
We consider the new divisor 54 and the new remainder 28,and apply the division lemma to get
54 = 28 x 1 + 26
We consider the new divisor 28 and the new remainder 26,and apply the division lemma to get
28 = 26 x 1 + 2
We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get
26 = 2 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 846 and 464 is 2
Notice that 2 = HCF(26,2) = HCF(28,26) = HCF(54,28) = HCF(82,54) = HCF(382,82) = HCF(464,382) = HCF(846,464) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 940 > 2, we apply the division lemma to 940 and 2, to get
940 = 2 x 470 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 940 is 2
Notice that 2 = HCF(940,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 58 > 2, we apply the division lemma to 58 and 2, to get
58 = 2 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 58 is 2
Notice that 2 = HCF(58,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
