HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 927, 254, 721 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 927, 254, 721 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 927, 254, 721 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 927, 254, 721 is 1.
HCF(927, 254, 721) = 1
HCF of 927, 254, 721 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 927, 254, 721 is 1.
Highest Common Factor of 927,254,721 is 1
Step 1: Since 927 > 254, we apply the division lemma to 927 and 254, to get
927 = 254 x 3 + 165
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 165 and 254, to get
254 = 165 x 1 + 89
Step 3: We consider the new divisor 165 and the new remainder 89, and apply the division lemma to get
165 = 89 x 1 + 76
We consider the new divisor 89 and the new remainder 76,and apply the division lemma to get
89 = 76 x 1 + 13
We consider the new divisor 76 and the new remainder 13,and apply the division lemma to get
76 = 13 x 5 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 927 and 254 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(76,13) = HCF(89,76) = HCF(165,89) = HCF(254,165) = HCF(927,254) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 721 > 1, we apply the division lemma to 721 and 1, to get
721 = 1 x 721 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 721 is 1
Notice that 1 = HCF(721,1) .
