HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 281, 725, 992 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 281, 725, 992 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 281, 725, 992 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 281, 725, 992 is 1.
HCF(281, 725, 992) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 281, 725, 992 is 1.
Step 1: Since 725 > 281, we apply the division lemma to 725 and 281, to get
725 = 281 x 2 + 163
Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 163 and 281, to get
281 = 163 x 1 + 118
Step 3: We consider the new divisor 163 and the new remainder 118, and apply the division lemma to get
163 = 118 x 1 + 45
We consider the new divisor 118 and the new remainder 45,and apply the division lemma to get
118 = 45 x 2 + 28
We consider the new divisor 45 and the new remainder 28,and apply the division lemma to get
45 = 28 x 1 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
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 281 and 725 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(45,28) = HCF(118,45) = HCF(163,118) = HCF(281,163) = HCF(725,281) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 992 > 1, we apply the division lemma to 992 and 1, to get
992 = 1 x 992 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 992 is 1
Notice that 1 = HCF(992,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
