HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 951, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 951, 305 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 557, 951, 305 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 557, 951, 305 is 1.
HCF(557, 951, 305) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 557, 951, 305 is 1.
Step 1: Since 951 > 557, we apply the division lemma to 951 and 557, to get
951 = 557 x 1 + 394
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 394 and 557, to get
557 = 394 x 1 + 163
Step 3: We consider the new divisor 394 and the new remainder 163, and apply the division lemma to get
394 = 163 x 2 + 68
We consider the new divisor 163 and the new remainder 68,and apply the division lemma to get
163 = 68 x 2 + 27
We consider the new divisor 68 and the new remainder 27,and apply the division lemma to get
68 = 27 x 2 + 14
We consider the new divisor 27 and the new remainder 14,and apply the division lemma to get
27 = 14 x 1 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 951 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(68,27) = HCF(163,68) = HCF(394,163) = HCF(557,394) = HCF(951,557) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 305 > 1, we apply the division lemma to 305 and 1, to get
305 = 1 x 305 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 305 is 1
Notice that 1 = HCF(305,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
