HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 555, 340, 88 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 555, 340, 88 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 819, 555, 340, 88 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 819, 555, 340, 88 is 1.
HCF(819, 555, 340, 88) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 555, 340, 88 is 1.
Step 1: Since 819 > 555, we apply the division lemma to 819 and 555, to get
819 = 555 x 1 + 264
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 264 and 555, to get
555 = 264 x 2 + 27
Step 3: We consider the new divisor 264 and the new remainder 27, and apply the division lemma to get
264 = 27 x 9 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 819 and 555 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(264,27) = HCF(555,264) = HCF(819,555) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 340 > 3, we apply the division lemma to 340 and 3, to get
340 = 3 x 113 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 340 is 1
Notice that 1 = HCF(3,1) = HCF(340,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 88 > 1, we apply the division lemma to 88 and 1, to get
88 = 1 x 88 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 88 is 1
Notice that 1 = HCF(88,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
