HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 714, 7581, 2000 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 714, 7581, 2000 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 714, 7581, 2000 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 714, 7581, 2000 is 1.
HCF(714, 7581, 2000) = 1
HCF of 714, 7581, 2000 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 714, 7581, 2000 is 1.
Highest Common Factor of 714,7581,2000 is 1
Step 1: Since 7581 > 714, we apply the division lemma to 7581 and 714, to get
7581 = 714 x 10 + 441
Step 2: Since the reminder 714 ≠ 0, we apply division lemma to 441 and 714, to get
714 = 441 x 1 + 273
Step 3: We consider the new divisor 441 and the new remainder 273, and apply the division lemma to get
441 = 273 x 1 + 168
We consider the new divisor 273 and the new remainder 168,and apply the division lemma to get
273 = 168 x 1 + 105
We consider the new divisor 168 and the new remainder 105,and apply the division lemma to get
168 = 105 x 1 + 63
We consider the new divisor 105 and the new remainder 63,and apply the division lemma to get
105 = 63 x 1 + 42
We consider the new divisor 63 and the new remainder 42,and apply the division lemma to get
63 = 42 x 1 + 21
We consider the new divisor 42 and the new remainder 21,and apply the division lemma to get
42 = 21 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 714 and 7581 is 21
Notice that 21 = HCF(42,21) = HCF(63,42) = HCF(105,63) = HCF(168,105) = HCF(273,168) = HCF(441,273) = HCF(714,441) = HCF(7581,714) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2000 > 21, we apply the division lemma to 2000 and 21, to get
2000 = 21 x 95 + 5
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 5 and 21, to get
21 = 5 x 4 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 21 and 2000 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(2000,21) .
