HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 384, 707 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 384, 707 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 665, 384, 707 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 665, 384, 707 is 1.
HCF(665, 384, 707) = 1
HCF of 665, 384, 707 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 384, 707 is 1.
Highest Common Factor of 665,384,707 is 1
Step 1: Since 665 > 384, we apply the division lemma to 665 and 384, to get
665 = 384 x 1 + 281
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 281 and 384, to get
384 = 281 x 1 + 103
Step 3: We consider the new divisor 281 and the new remainder 103, and apply the division lemma to get
281 = 103 x 2 + 75
We consider the new divisor 103 and the new remainder 75,and apply the division lemma to get
103 = 75 x 1 + 28
We consider the new divisor 75 and the new remainder 28,and apply the division lemma to get
75 = 28 x 2 + 19
We consider the new divisor 28 and the new remainder 19,and apply the division lemma to get
28 = 19 x 1 + 9
We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get
19 = 9 x 2 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 665 and 384 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(28,19) = HCF(75,28) = HCF(103,75) = HCF(281,103) = HCF(384,281) = HCF(665,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 707 > 1, we apply the division lemma to 707 and 1, to get
707 = 1 x 707 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 707 is 1
Notice that 1 = HCF(707,1) .
