HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 5733, 1571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 5733, 1571 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 640, 5733, 1571 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 640, 5733, 1571 is 1.
HCF(640, 5733, 1571) = 1
HCF of 640, 5733, 1571 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 640, 5733, 1571 is 1.
Highest Common Factor of 640,5733,1571 is 1
Step 1: Since 5733 > 640, we apply the division lemma to 5733 and 640, to get
5733 = 640 x 8 + 613
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 613 and 640, to get
640 = 613 x 1 + 27
Step 3: We consider the new divisor 613 and the new remainder 27, and apply the division lemma to get
613 = 27 x 22 + 19
We consider the new divisor 27 and the new remainder 19,and apply the division lemma to get
27 = 19 x 1 + 8
We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get
19 = 8 x 2 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 640 and 5733 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(27,19) = HCF(613,27) = HCF(640,613) = HCF(5733,640) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1571 > 1, we apply the division lemma to 1571 and 1, to get
1571 = 1 x 1571 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1571 is 1
Notice that 1 = HCF(1571,1) .
