HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 328, 693, 540, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 328, 693, 540, 189 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 328, 693, 540, 189 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 328, 693, 540, 189 is 1.
HCF(328, 693, 540, 189) = 1
HCF of 328, 693, 540, 189 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 328, 693, 540, 189 is 1.
Highest Common Factor of 328,693,540,189 is 1
Step 1: Since 693 > 328, we apply the division lemma to 693 and 328, to get
693 = 328 x 2 + 37
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 37 and 328, to get
328 = 37 x 8 + 32
Step 3: We consider the new divisor 37 and the new remainder 32, and apply the division lemma to get
37 = 32 x 1 + 5
We consider the new divisor 32 and the new remainder 5,and apply the division lemma to get
32 = 5 x 6 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 328 and 693 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(37,32) = HCF(328,37) = HCF(693,328) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 1, we apply the division lemma to 540 and 1, to get
540 = 1 x 540 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 540 is 1
Notice that 1 = HCF(540,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get
189 = 1 x 189 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1
Notice that 1 = HCF(189,1) .
