HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 716, 990, 783 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 716, 990, 783 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 716, 990, 783 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 716, 990, 783 is 1.
HCF(716, 990, 783) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 716, 990, 783 is 1.
Step 1: Since 990 > 716, we apply the division lemma to 990 and 716, to get
990 = 716 x 1 + 274
Step 2: Since the reminder 716 ≠ 0, we apply division lemma to 274 and 716, to get
716 = 274 x 2 + 168
Step 3: We consider the new divisor 274 and the new remainder 168, and apply the division lemma to get
274 = 168 x 1 + 106
We consider the new divisor 168 and the new remainder 106,and apply the division lemma to get
168 = 106 x 1 + 62
We consider the new divisor 106 and the new remainder 62,and apply the division lemma to get
106 = 62 x 1 + 44
We consider the new divisor 62 and the new remainder 44,and apply the division lemma to get
62 = 44 x 1 + 18
We consider the new divisor 44 and the new remainder 18,and apply the division lemma to get
44 = 18 x 2 + 8
We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get
18 = 8 x 2 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 716 and 990 is 2
Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(44,18) = HCF(62,44) = HCF(106,62) = HCF(168,106) = HCF(274,168) = HCF(716,274) = HCF(990,716) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 783 > 2, we apply the division lemma to 783 and 2, to get
783 = 2 x 391 + 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 783 is 1
Notice that 1 = HCF(2,1) = HCF(783,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
