HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 281, 173, 570 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 281, 173, 570 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, 173, 570 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, 173, 570 is 1.
HCF(281, 173, 570) = 1
HCF of 281, 173, 570 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 281, 173, 570 is 1.
Highest Common Factor of 281,173,570 is 1
Step 1: Since 281 > 173, we apply the division lemma to 281 and 173, to get
281 = 173 x 1 + 108
Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 108 and 173, to get
173 = 108 x 1 + 65
Step 3: We consider the new divisor 108 and the new remainder 65, and apply the division lemma to get
108 = 65 x 1 + 43
We consider the new divisor 65 and the new remainder 43,and apply the division lemma to get
65 = 43 x 1 + 22
We consider the new divisor 43 and the new remainder 22,and apply the division lemma to get
43 = 22 x 1 + 21
We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get
22 = 21 x 1 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 281 and 173 is 1
Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(43,22) = HCF(65,43) = HCF(108,65) = HCF(173,108) = HCF(281,173) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 570 > 1, we apply the division lemma to 570 and 1, to get
570 = 1 x 570 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 570 is 1
Notice that 1 = HCF(570,1) .
