HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 780, 43, 259 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 555, 780, 43, 259 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 555, 780, 43, 259 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 555, 780, 43, 259 is 1.
HCF(555, 780, 43, 259) = 1
HCF of 555, 780, 43, 259 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 555, 780, 43, 259 is 1.
Highest Common Factor of 555,780,43,259 is 1
Step 1: Since 780 > 555, we apply the division lemma to 780 and 555, to get
780 = 555 x 1 + 225
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 225 and 555, to get
555 = 225 x 2 + 105
Step 3: We consider the new divisor 225 and the new remainder 105, and apply the division lemma to get
225 = 105 x 2 + 15
We consider the new divisor 105 and the new remainder 15, and apply the division lemma to get
105 = 15 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 555 and 780 is 15
Notice that 15 = HCF(105,15) = HCF(225,105) = HCF(555,225) = HCF(780,555) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 43 > 15, we apply the division lemma to 43 and 15, to get
43 = 15 x 2 + 13
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 13 and 15, to get
15 = 13 x 1 + 2
Step 3: We consider the new divisor 13 and the new remainder 2, and apply the division lemma to get
13 = 2 x 6 + 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 15 and 43 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(43,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 259 > 1, we apply the division lemma to 259 and 1, to get
259 = 1 x 259 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 259 is 1
Notice that 1 = HCF(259,1) .
