HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 954, 615, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 954, 615, 439 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 954, 615, 439 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 954, 615, 439 is 1.
HCF(954, 615, 439) = 1
HCF of 954, 615, 439 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 954, 615, 439 is 1.
Highest Common Factor of 954,615,439 is 1
Step 1: Since 954 > 615, we apply the division lemma to 954 and 615, to get
954 = 615 x 1 + 339
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 339 and 615, to get
615 = 339 x 1 + 276
Step 3: We consider the new divisor 339 and the new remainder 276, and apply the division lemma to get
339 = 276 x 1 + 63
We consider the new divisor 276 and the new remainder 63,and apply the division lemma to get
276 = 63 x 4 + 24
We consider the new divisor 63 and the new remainder 24,and apply the division lemma to get
63 = 24 x 2 + 15
We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get
24 = 15 x 1 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 954 and 615 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(63,24) = HCF(276,63) = HCF(339,276) = HCF(615,339) = HCF(954,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 3, we apply the division lemma to 439 and 3, to get
439 = 3 x 146 + 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 439 is 1
Notice that 1 = HCF(3,1) = HCF(439,3) .
