HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 195, 633 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 195, 633 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, 195, 633 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, 195, 633 is 1.
HCF(640, 195, 633) = 1
HCF of 640, 195, 633 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, 195, 633 is 1.
Highest Common Factor of 640,195,633 is 1
Step 1: Since 640 > 195, we apply the division lemma to 640 and 195, to get
640 = 195 x 3 + 55
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 55 and 195, to get
195 = 55 x 3 + 30
Step 3: We consider the new divisor 55 and the new remainder 30, and apply the division lemma to get
55 = 30 x 1 + 25
We consider the new divisor 30 and the new remainder 25,and apply the division lemma to get
30 = 25 x 1 + 5
We consider the new divisor 25 and the new remainder 5,and apply the division lemma to get
25 = 5 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 640 and 195 is 5
Notice that 5 = HCF(25,5) = HCF(30,25) = HCF(55,30) = HCF(195,55) = HCF(640,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 633 > 5, we apply the division lemma to 633 and 5, to get
633 = 5 x 126 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 633 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(633,5) .
