HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 315, 56 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 315, 56 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 494, 315, 56 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 494, 315, 56 is 1.
HCF(494, 315, 56) = 1
HCF of 494, 315, 56 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 315, 56 is 1.
Highest Common Factor of 494,315,56 is 1
Step 1: Since 494 > 315, we apply the division lemma to 494 and 315, to get
494 = 315 x 1 + 179
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 179 and 315, to get
315 = 179 x 1 + 136
Step 3: We consider the new divisor 179 and the new remainder 136, and apply the division lemma to get
179 = 136 x 1 + 43
We consider the new divisor 136 and the new remainder 43,and apply the division lemma to get
136 = 43 x 3 + 7
We consider the new divisor 43 and the new remainder 7,and apply the division lemma to get
43 = 7 x 6 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 494 and 315 is 1
Notice that 1 = HCF(7,1) = HCF(43,7) = HCF(136,43) = HCF(179,136) = HCF(315,179) = HCF(494,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 56 > 1, we apply the division lemma to 56 and 1, to get
56 = 1 x 56 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 56 is 1
Notice that 1 = HCF(56,1) .
