HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 250, 700, 170 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 250, 700, 170 is 10 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 250, 700, 170 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 250, 700, 170 is 10.
HCF(250, 700, 170) = 10
HCF of 250, 700, 170 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 250, 700, 170 is 10.
Highest Common Factor of 250,700,170 is 10
Step 1: Since 700 > 250, we apply the division lemma to 700 and 250, to get
700 = 250 x 2 + 200
Step 2: Since the reminder 250 ≠ 0, we apply division lemma to 200 and 250, to get
250 = 200 x 1 + 50
Step 3: We consider the new divisor 200 and the new remainder 50, and apply the division lemma to get
200 = 50 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 50, the HCF of 250 and 700 is 50
Notice that 50 = HCF(200,50) = HCF(250,200) = HCF(700,250) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 170 > 50, we apply the division lemma to 170 and 50, to get
170 = 50 x 3 + 20
Step 2: Since the reminder 50 ≠ 0, we apply division lemma to 20 and 50, to get
50 = 20 x 2 + 10
Step 3: We consider the new divisor 20 and the new remainder 10, and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 50 and 170 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(170,50) .
