HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 919 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 919 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 490, 919 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, 919 is 1.
HCF(490, 919) = 1
HCF of 490, 919 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, 919 is 1.
Highest Common Factor of 490,919 is 1
Step 1: Since 919 > 490, we apply the division lemma to 919 and 490, to get
919 = 490 x 1 + 429
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 429 and 490, to get
490 = 429 x 1 + 61
Step 3: We consider the new divisor 429 and the new remainder 61, and apply the division lemma to get
429 = 61 x 7 + 2
We consider the new divisor 61 and the new remainder 2,and apply the division lemma to get
61 = 2 x 30 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 490 and 919 is 1
Notice that 1 = HCF(2,1) = HCF(61,2) = HCF(429,61) = HCF(490,429) = HCF(919,490) .
