HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 553, 719 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 553, 719 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 855, 553, 719 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 855, 553, 719 is 1.
HCF(855, 553, 719) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 855, 553, 719 is 1.
Step 1: Since 855 > 553, we apply the division lemma to 855 and 553, to get
855 = 553 x 1 + 302
Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 302 and 553, to get
553 = 302 x 1 + 251
Step 3: We consider the new divisor 302 and the new remainder 251, and apply the division lemma to get
302 = 251 x 1 + 51
We consider the new divisor 251 and the new remainder 51,and apply the division lemma to get
251 = 51 x 4 + 47
We consider the new divisor 51 and the new remainder 47,and apply the division lemma to get
51 = 47 x 1 + 4
We consider the new divisor 47 and the new remainder 4,and apply the division lemma to get
47 = 4 x 11 + 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 855 and 553 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(47,4) = HCF(51,47) = HCF(251,51) = HCF(302,251) = HCF(553,302) = HCF(855,553) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 719 > 1, we apply the division lemma to 719 and 1, to get
719 = 1 x 719 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 719 is 1
Notice that 1 = HCF(719,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
