HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 158, 573, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 158, 573, 349 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 158, 573, 349 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 158, 573, 349 is 1.
HCF(158, 573, 349) = 1
HCF of 158, 573, 349 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 158, 573, 349 is 1.
Highest Common Factor of 158,573,349 is 1
Step 1: Since 573 > 158, we apply the division lemma to 573 and 158, to get
573 = 158 x 3 + 99
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 99 and 158, to get
158 = 99 x 1 + 59
Step 3: We consider the new divisor 99 and the new remainder 59, and apply the division lemma to get
99 = 59 x 1 + 40
We consider the new divisor 59 and the new remainder 40,and apply the division lemma to get
59 = 40 x 1 + 19
We consider the new divisor 40 and the new remainder 19,and apply the division lemma to get
40 = 19 x 2 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 158 and 573 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(40,19) = HCF(59,40) = HCF(99,59) = HCF(158,99) = HCF(573,158) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 349 > 1, we apply the division lemma to 349 and 1, to get
349 = 1 x 349 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 349 is 1
Notice that 1 = HCF(349,1) .
