HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 703, 453, 99 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 703, 453, 99 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 490, 703, 453, 99 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 490, 703, 453, 99 is 1.
HCF(490, 703, 453, 99) = 1
HCF of 490, 703, 453, 99 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 703, 453, 99 is 1.
Highest Common Factor of 490,703,453,99 is 1
Step 1: Since 703 > 490, we apply the division lemma to 703 and 490, to get
703 = 490 x 1 + 213
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 213 and 490, to get
490 = 213 x 2 + 64
Step 3: We consider the new divisor 213 and the new remainder 64, and apply the division lemma to get
213 = 64 x 3 + 21
We consider the new divisor 64 and the new remainder 21,and apply the division lemma to get
64 = 21 x 3 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 490 and 703 is 1
Notice that 1 = HCF(21,1) = HCF(64,21) = HCF(213,64) = HCF(490,213) = HCF(703,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 453 > 1, we apply the division lemma to 453 and 1, to get
453 = 1 x 453 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 453 is 1
Notice that 1 = HCF(453,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99 > 1, we apply the division lemma to 99 and 1, to get
99 = 1 x 99 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 99 is 1
Notice that 1 = HCF(99,1) .
