HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 890 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 890 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 490, 890 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 490, 890 is 10.
HCF(490, 890) = 10
HCF of 490, 890 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 890 is 10.
Highest Common Factor of 490,890 is 10
Step 1: Since 890 > 490, we apply the division lemma to 890 and 490, to get
890 = 490 x 1 + 400
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 400 and 490, to get
490 = 400 x 1 + 90
Step 3: We consider the new divisor 400 and the new remainder 90, and apply the division lemma to get
400 = 90 x 4 + 40
We consider the new divisor 90 and the new remainder 40,and apply the division lemma to get
90 = 40 x 2 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 490 and 890 is 10
Notice that 10 = HCF(40,10) = HCF(90,40) = HCF(400,90) = HCF(490,400) = HCF(890,490) .
