HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 415, 706 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 415, 706 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, 415, 706 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, 415, 706 is 1.
HCF(658, 415, 706) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 658, 415, 706 is 1.
Step 1: Since 658 > 415, we apply the division lemma to 658 and 415, to get
658 = 415 x 1 + 243
Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 243 and 415, to get
415 = 243 x 1 + 172
Step 3: We consider the new divisor 243 and the new remainder 172, and apply the division lemma to get
243 = 172 x 1 + 71
We consider the new divisor 172 and the new remainder 71,and apply the division lemma to get
172 = 71 x 2 + 30
We consider the new divisor 71 and the new remainder 30,and apply the division lemma to get
71 = 30 x 2 + 11
We consider the new divisor 30 and the new remainder 11,and apply the division lemma to get
30 = 11 x 2 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 658 and 415 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(30,11) = HCF(71,30) = HCF(172,71) = HCF(243,172) = HCF(415,243) = HCF(658,415) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 706 > 1, we apply the division lemma to 706 and 1, to get
706 = 1 x 706 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 706 is 1
Notice that 1 = HCF(706,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
