HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 570, 890, 846 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 570, 890, 846 is 2 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 570, 890, 846 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 570, 890, 846 is 2.
HCF(570, 890, 846) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 570, 890, 846 is 2.
Step 1: Since 890 > 570, we apply the division lemma to 890 and 570, to get
890 = 570 x 1 + 320
Step 2: Since the reminder 570 ≠ 0, we apply division lemma to 320 and 570, to get
570 = 320 x 1 + 250
Step 3: We consider the new divisor 320 and the new remainder 250, and apply the division lemma to get
320 = 250 x 1 + 70
We consider the new divisor 250 and the new remainder 70,and apply the division lemma to get
250 = 70 x 3 + 40
We consider the new divisor 70 and the new remainder 40,and apply the division lemma to get
70 = 40 x 1 + 30
We consider the new divisor 40 and the new remainder 30,and apply the division lemma to get
40 = 30 x 1 + 10
We consider the new divisor 30 and the new remainder 10,and apply the division lemma to get
30 = 10 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 570 and 890 is 10
Notice that 10 = HCF(30,10) = HCF(40,30) = HCF(70,40) = HCF(250,70) = HCF(320,250) = HCF(570,320) = HCF(890,570) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 846 > 10, we apply the division lemma to 846 and 10, to get
846 = 10 x 84 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 846 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(846,10) .
Here are some samples of HCF using Euclid's Algorithm calculations.
