HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 254, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 254, 915 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 254, 915 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 254, 915 is 1.
HCF(254, 915) = 1
HCF of 254, 915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 254, 915 is 1.
Highest Common Factor of 254,915 is 1
Step 1: Since 915 > 254, we apply the division lemma to 915 and 254, to get
915 = 254 x 3 + 153
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 153 and 254, to get
254 = 153 x 1 + 101
Step 3: We consider the new divisor 153 and the new remainder 101, and apply the division lemma to get
153 = 101 x 1 + 52
We consider the new divisor 101 and the new remainder 52,and apply the division lemma to get
101 = 52 x 1 + 49
We consider the new divisor 52 and the new remainder 49,and apply the division lemma to get
52 = 49 x 1 + 3
We consider the new divisor 49 and the new remainder 3,and apply the division lemma to get
49 = 3 x 16 + 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 254 and 915 is 1
Notice that 1 = HCF(3,1) = HCF(49,3) = HCF(52,49) = HCF(101,52) = HCF(153,101) = HCF(254,153) = HCF(915,254) .
