HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 875, 640, 514, 786 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 875, 640, 514, 786 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 875, 640, 514, 786 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 875, 640, 514, 786 is 1.
HCF(875, 640, 514, 786) = 1
HCF of 875, 640, 514, 786 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 875, 640, 514, 786 is 1.
Highest Common Factor of 875,640,514,786 is 1
Step 1: Since 875 > 640, we apply the division lemma to 875 and 640, to get
875 = 640 x 1 + 235
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 235 and 640, to get
640 = 235 x 2 + 170
Step 3: We consider the new divisor 235 and the new remainder 170, and apply the division lemma to get
235 = 170 x 1 + 65
We consider the new divisor 170 and the new remainder 65,and apply the division lemma to get
170 = 65 x 2 + 40
We consider the new divisor 65 and the new remainder 40,and apply the division lemma to get
65 = 40 x 1 + 25
We consider the new divisor 40 and the new remainder 25,and apply the division lemma to get
40 = 25 x 1 + 15
We consider the new divisor 25 and the new remainder 15,and apply the division lemma to get
25 = 15 x 1 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 875 and 640 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(40,25) = HCF(65,40) = HCF(170,65) = HCF(235,170) = HCF(640,235) = HCF(875,640) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 514 > 5, we apply the division lemma to 514 and 5, to get
514 = 5 x 102 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 514 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(514,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 786 > 1, we apply the division lemma to 786 and 1, to get
786 = 1 x 786 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 786 is 1
Notice that 1 = HCF(786,1) .
