HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 500, 646, 456 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 500, 646, 456 is 2 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 500, 646, 456 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 500, 646, 456 is 2.
HCF(500, 646, 456) = 2
HCF of 500, 646, 456 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 500, 646, 456 is 2.
Highest Common Factor of 500,646,456 is 2
Step 1: Since 646 > 500, we apply the division lemma to 646 and 500, to get
646 = 500 x 1 + 146
Step 2: Since the reminder 500 ≠ 0, we apply division lemma to 146 and 500, to get
500 = 146 x 3 + 62
Step 3: We consider the new divisor 146 and the new remainder 62, and apply the division lemma to get
146 = 62 x 2 + 22
We consider the new divisor 62 and the new remainder 22,and apply the division lemma to get
62 = 22 x 2 + 18
We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get
22 = 18 x 1 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 500 and 646 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(62,22) = HCF(146,62) = HCF(500,146) = HCF(646,500) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 456 > 2, we apply the division lemma to 456 and 2, to get
456 = 2 x 228 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 456 is 2
Notice that 2 = HCF(456,2) .
