HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 619, 68 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 619, 68 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 619, 68 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 619, 68 is 1.
HCF(619, 68) = 1
HCF of 619, 68 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 619, 68 is 1.
Highest Common Factor of 619,68 is 1
Step 1: Since 619 > 68, we apply the division lemma to 619 and 68, to get
619 = 68 x 9 + 7
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 7 and 68, to get
68 = 7 x 9 + 5
Step 3: We consider the new divisor 7 and the new remainder 5, and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 619 and 68 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(68,7) = HCF(619,68) .
