HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 525, 694, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 525, 694, 543 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 525, 694, 543 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 525, 694, 543 is 1.
HCF(525, 694, 543) = 1
HCF of 525, 694, 543 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 525, 694, 543 is 1.
Highest Common Factor of 525,694,543 is 1
Step 1: Since 694 > 525, we apply the division lemma to 694 and 525, to get
694 = 525 x 1 + 169
Step 2: Since the reminder 525 ≠ 0, we apply division lemma to 169 and 525, to get
525 = 169 x 3 + 18
Step 3: We consider the new divisor 169 and the new remainder 18, and apply the division lemma to get
169 = 18 x 9 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 525 and 694 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(169,18) = HCF(525,169) = HCF(694,525) .
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) .
