HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 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 658, 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 658, 619 is 1.
HCF(658, 619) = 1
HCF of 658, 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 658, 619 is 1.
Highest Common Factor of 658,619 is 1
Step 1: Since 658 > 619, we apply the division lemma to 658 and 619, to get
658 = 619 x 1 + 39
Step 2: Since the reminder 619 ≠ 0, we apply division lemma to 39 and 619, to get
619 = 39 x 15 + 34
Step 3: We consider the new divisor 39 and the new remainder 34, and apply the division lemma to get
39 = 34 x 1 + 5
We consider the new divisor 34 and the new remainder 5,and apply the division lemma to get
34 = 5 x 6 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 658 and 619 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(34,5) = HCF(39,34) = HCF(619,39) = HCF(658,619) .
