HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 281, 682, 504 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 170, 281, 682, 504 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 170, 281, 682, 504 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 170, 281, 682, 504 is 1.
HCF(170, 281, 682, 504) = 1
HCF of 170, 281, 682, 504 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 170, 281, 682, 504 is 1.
Highest Common Factor of 170,281,682,504 is 1
Step 1: Since 281 > 170, we apply the division lemma to 281 and 170, to get
281 = 170 x 1 + 111
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 111 and 170, to get
170 = 111 x 1 + 59
Step 3: We consider the new divisor 111 and the new remainder 59, and apply the division lemma to get
111 = 59 x 1 + 52
We consider the new divisor 59 and the new remainder 52,and apply the division lemma to get
59 = 52 x 1 + 7
We consider the new divisor 52 and the new remainder 7,and apply the division lemma to get
52 = 7 x 7 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 170 and 281 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(52,7) = HCF(59,52) = HCF(111,59) = HCF(170,111) = HCF(281,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 682 > 1, we apply the division lemma to 682 and 1, to get
682 = 1 x 682 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 682 is 1
Notice that 1 = HCF(682,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 504 > 1, we apply the division lemma to 504 and 1, to get
504 = 1 x 504 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 504 is 1
Notice that 1 = HCF(504,1) .
