HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 291, 496, 52 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 291, 496, 52 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 342, 291, 496, 52 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 342, 291, 496, 52 is 1.
HCF(342, 291, 496, 52) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 291, 496, 52 is 1.
Step 1: Since 342 > 291, we apply the division lemma to 342 and 291, to get
342 = 291 x 1 + 51
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 51 and 291, to get
291 = 51 x 5 + 36
Step 3: We consider the new divisor 51 and the new remainder 36, and apply the division lemma to get
51 = 36 x 1 + 15
We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get
36 = 15 x 2 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 342 and 291 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(51,36) = HCF(291,51) = HCF(342,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 496 > 3, we apply the division lemma to 496 and 3, to get
496 = 3 x 165 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 496 is 1
Notice that 1 = HCF(3,1) = HCF(496,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 52 > 1, we apply the division lemma to 52 and 1, to get
52 = 1 x 52 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 52 is 1
Notice that 1 = HCF(52,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
