HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 716, 635, 990 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 716, 635, 990 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, 635, 990 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, 635, 990 is 1.
HCF(716, 635, 990) = 1
HCF of 716, 635, 990 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 716, 635, 990 is 1.
Highest Common Factor of 716,635,990 is 1
Step 1: Since 716 > 635, we apply the division lemma to 716 and 635, to get
716 = 635 x 1 + 81
Step 2: Since the reminder 635 ≠ 0, we apply division lemma to 81 and 635, to get
635 = 81 x 7 + 68
Step 3: We consider the new divisor 81 and the new remainder 68, and apply the division lemma to get
81 = 68 x 1 + 13
We consider the new divisor 68 and the new remainder 13,and apply the division lemma to get
68 = 13 x 5 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 716 and 635 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(68,13) = HCF(81,68) = HCF(635,81) = HCF(716,635) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 990 > 1, we apply the division lemma to 990 and 1, to get
990 = 1 x 990 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 990 is 1
Notice that 1 = HCF(990,1) .
