HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 619 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 493, 619 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 493, 619 is 1.
HCF(493, 619) = 1
HCF of 493, 619 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 619 is 1.
Highest Common Factor of 493,619 is 1
Step 1: Since 619 > 493, we apply the division lemma to 619 and 493, to get
619 = 493 x 1 + 126
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 126 and 493, to get
493 = 126 x 3 + 115
Step 3: We consider the new divisor 126 and the new remainder 115, and apply the division lemma to get
126 = 115 x 1 + 11
We consider the new divisor 115 and the new remainder 11,and apply the division lemma to get
115 = 11 x 10 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 619 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(115,11) = HCF(126,115) = HCF(493,126) = HCF(619,493) .
