HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 459, 543, 348 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 459, 543, 348 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 634, 459, 543, 348 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 634, 459, 543, 348 is 1.
HCF(634, 459, 543, 348) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 459, 543, 348 is 1.
Step 1: Since 634 > 459, we apply the division lemma to 634 and 459, to get
634 = 459 x 1 + 175
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 175 and 459, to get
459 = 175 x 2 + 109
Step 3: We consider the new divisor 175 and the new remainder 109, and apply the division lemma to get
175 = 109 x 1 + 66
We consider the new divisor 109 and the new remainder 66,and apply the division lemma to get
109 = 66 x 1 + 43
We consider the new divisor 66 and the new remainder 43,and apply the division lemma to get
66 = 43 x 1 + 23
We consider the new divisor 43 and the new remainder 23,and apply the division lemma to get
43 = 23 x 1 + 20
We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get
23 = 20 x 1 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 634 and 459 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(66,43) = HCF(109,66) = HCF(175,109) = HCF(459,175) = HCF(634,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 543 > 1, we apply the division lemma to 543 and 1, to get
543 = 1 x 543 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 543 is 1
Notice that 1 = HCF(543,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 348 > 1, we apply the division lemma to 348 and 1, to get
348 = 1 x 348 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 348 is 1
Notice that 1 = HCF(348,1) .
