HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 255, 951, 487, 187 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 255, 951, 487, 187 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 255, 951, 487, 187 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 255, 951, 487, 187 is 1.
HCF(255, 951, 487, 187) = 1
HCF of 255, 951, 487, 187 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 255, 951, 487, 187 is 1.
Highest Common Factor of 255,951,487,187 is 1
Step 1: Since 951 > 255, we apply the division lemma to 951 and 255, to get
951 = 255 x 3 + 186
Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 186 and 255, to get
255 = 186 x 1 + 69
Step 3: We consider the new divisor 186 and the new remainder 69, and apply the division lemma to get
186 = 69 x 2 + 48
We consider the new divisor 69 and the new remainder 48,and apply the division lemma to get
69 = 48 x 1 + 21
We consider the new divisor 48 and the new remainder 21,and apply the division lemma to get
48 = 21 x 2 + 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 255 and 951 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(48,21) = HCF(69,48) = HCF(186,69) = HCF(255,186) = HCF(951,255) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 487 > 3, we apply the division lemma to 487 and 3, to get
487 = 3 x 162 + 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 487 is 1
Notice that 1 = HCF(3,1) = HCF(487,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 187 > 1, we apply the division lemma to 187 and 1, to get
187 = 1 x 187 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 187 is 1
Notice that 1 = HCF(187,1) .
