HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 788, 154 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 788, 154 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 487, 788, 154 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 487, 788, 154 is 1.
HCF(487, 788, 154) = 1
HCF of 487, 788, 154 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 788, 154 is 1.
Highest Common Factor of 487,788,154 is 1
Step 1: Since 788 > 487, we apply the division lemma to 788 and 487, to get
788 = 487 x 1 + 301
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 301 and 487, to get
487 = 301 x 1 + 186
Step 3: We consider the new divisor 301 and the new remainder 186, and apply the division lemma to get
301 = 186 x 1 + 115
We consider the new divisor 186 and the new remainder 115,and apply the division lemma to get
186 = 115 x 1 + 71
We consider the new divisor 115 and the new remainder 71,and apply the division lemma to get
115 = 71 x 1 + 44
We consider the new divisor 71 and the new remainder 44,and apply the division lemma to get
71 = 44 x 1 + 27
We consider the new divisor 44 and the new remainder 27,and apply the division lemma to get
44 = 27 x 1 + 17
We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get
27 = 17 x 1 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 487 and 788 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(44,27) = HCF(71,44) = HCF(115,71) = HCF(186,115) = HCF(301,186) = HCF(487,301) = HCF(788,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 154 > 1, we apply the division lemma to 154 and 1, to get
154 = 1 x 154 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 154 is 1
Notice that 1 = HCF(154,1) .
