HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 74315 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 74315 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 679, 74315 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 679, 74315 is 1.
HCF(679, 74315) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 679, 74315 is 1.
Step 1: Since 74315 > 679, we apply the division lemma to 74315 and 679, to get
74315 = 679 x 109 + 304
Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 304 and 679, to get
679 = 304 x 2 + 71
Step 3: We consider the new divisor 304 and the new remainder 71, and apply the division lemma to get
304 = 71 x 4 + 20
We consider the new divisor 71 and the new remainder 20,and apply the division lemma to get
71 = 20 x 3 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 679 and 74315 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(71,20) = HCF(304,71) = HCF(679,304) = HCF(74315,679) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
