HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 140, 404, 281 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 140, 404, 281 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 140, 404, 281 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 140, 404, 281 is 1.
HCF(140, 404, 281) = 1
HCF of 140, 404, 281 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 140, 404, 281 is 1.
Highest Common Factor of 140,404,281 is 1
Step 1: Since 404 > 140, we apply the division lemma to 404 and 140, to get
404 = 140 x 2 + 124
Step 2: Since the reminder 140 ≠ 0, we apply division lemma to 124 and 140, to get
140 = 124 x 1 + 16
Step 3: We consider the new divisor 124 and the new remainder 16, and apply the division lemma to get
124 = 16 x 7 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 140 and 404 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(124,16) = HCF(140,124) = HCF(404,140) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 281 > 4, we apply the division lemma to 281 and 4, to get
281 = 4 x 70 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 281 is 1
Notice that 1 = HCF(4,1) = HCF(281,4) .
