HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 818, 963 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 818, 963 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 456, 818, 963 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 456, 818, 963 is 1.
HCF(456, 818, 963) = 1
HCF of 456, 818, 963 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 818, 963 is 1.
Highest Common Factor of 456,818,963 is 1
Step 1: Since 818 > 456, we apply the division lemma to 818 and 456, to get
818 = 456 x 1 + 362
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 362 and 456, to get
456 = 362 x 1 + 94
Step 3: We consider the new divisor 362 and the new remainder 94, and apply the division lemma to get
362 = 94 x 3 + 80
We consider the new divisor 94 and the new remainder 80,and apply the division lemma to get
94 = 80 x 1 + 14
We consider the new divisor 80 and the new remainder 14,and apply the division lemma to get
80 = 14 x 5 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 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 456 and 818 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(80,14) = HCF(94,80) = HCF(362,94) = HCF(456,362) = HCF(818,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 963 > 2, we apply the division lemma to 963 and 2, to get
963 = 2 x 481 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 963 is 1
Notice that 1 = HCF(2,1) = HCF(963,2) .
