HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 709, 40, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 709, 40, 555 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 709, 40, 555 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 709, 40, 555 is 1.
HCF(709, 40, 555) = 1
HCF of 709, 40, 555 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 709, 40, 555 is 1.
Highest Common Factor of 709,40,555 is 1
Step 1: Since 709 > 40, we apply the division lemma to 709 and 40, to get
709 = 40 x 17 + 29
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 29 and 40, to get
40 = 29 x 1 + 11
Step 3: We consider the new divisor 29 and the new remainder 11, and apply the division lemma to get
29 = 11 x 2 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 709 and 40 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(40,29) = HCF(709,40) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 555 > 1, we apply the division lemma to 555 and 1, to get
555 = 1 x 555 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 555 is 1
Notice that 1 = HCF(555,1) .
