HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 704, 618, 557 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 704, 618, 557 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 704, 618, 557 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 704, 618, 557 is 1.
HCF(704, 618, 557) = 1
HCF of 704, 618, 557 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 704, 618, 557 is 1.
Highest Common Factor of 704,618,557 is 1
Step 1: Since 704 > 618, we apply the division lemma to 704 and 618, to get
704 = 618 x 1 + 86
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 86 and 618, to get
618 = 86 x 7 + 16
Step 3: We consider the new divisor 86 and the new remainder 16, and apply the division lemma to get
86 = 16 x 5 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 704 and 618 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(86,16) = HCF(618,86) = HCF(704,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 557 > 2, we apply the division lemma to 557 and 2, to get
557 = 2 x 278 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 557 is 1
Notice that 1 = HCF(2,1) = HCF(557,2) .
