HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 653, 581, 16 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 253, 653, 581, 16 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 253, 653, 581, 16 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 253, 653, 581, 16 is 1.
HCF(253, 653, 581, 16) = 1
HCF of 253, 653, 581, 16 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 253, 653, 581, 16 is 1.
Highest Common Factor of 253,653,581,16 is 1
Step 1: Since 653 > 253, we apply the division lemma to 653 and 253, to get
653 = 253 x 2 + 147
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 147 and 253, to get
253 = 147 x 1 + 106
Step 3: We consider the new divisor 147 and the new remainder 106, and apply the division lemma to get
147 = 106 x 1 + 41
We consider the new divisor 106 and the new remainder 41,and apply the division lemma to get
106 = 41 x 2 + 24
We consider the new divisor 41 and the new remainder 24,and apply the division lemma to get
41 = 24 x 1 + 17
We consider the new divisor 24 and the new remainder 17,and apply the division lemma to get
24 = 17 x 1 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 253 and 653 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(24,17) = HCF(41,24) = HCF(106,41) = HCF(147,106) = HCF(253,147) = HCF(653,253) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 581 > 1, we apply the division lemma to 581 and 1, to get
581 = 1 x 581 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 581 is 1
Notice that 1 = HCF(581,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 16 > 1, we apply the division lemma to 16 and 1, to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 16 is 1
Notice that 1 = HCF(16,1) .
