HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 578, 359 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 578, 359 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 578, 359 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 578, 359 is 1.
HCF(578, 359) = 1
HCF of 578, 359 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 578, 359 is 1.
Highest Common Factor of 578,359 is 1
Step 1: Since 578 > 359, we apply the division lemma to 578 and 359, to get
578 = 359 x 1 + 219
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 219 and 359, to get
359 = 219 x 1 + 140
Step 3: We consider the new divisor 219 and the new remainder 140, and apply the division lemma to get
219 = 140 x 1 + 79
We consider the new divisor 140 and the new remainder 79,and apply the division lemma to get
140 = 79 x 1 + 61
We consider the new divisor 79 and the new remainder 61,and apply the division lemma to get
79 = 61 x 1 + 18
We consider the new divisor 61 and the new remainder 18,and apply the division lemma to get
61 = 18 x 3 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 578 and 359 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(61,18) = HCF(79,61) = HCF(140,79) = HCF(219,140) = HCF(359,219) = HCF(578,359) .
