HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 573, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 573, 18 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 770, 573, 18 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 770, 573, 18 is 1.
HCF(770, 573, 18) = 1
HCF of 770, 573, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 573, 18 is 1.
Highest Common Factor of 770,573,18 is 1
Step 1: Since 770 > 573, we apply the division lemma to 770 and 573, to get
770 = 573 x 1 + 197
Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 197 and 573, to get
573 = 197 x 2 + 179
Step 3: We consider the new divisor 197 and the new remainder 179, and apply the division lemma to get
197 = 179 x 1 + 18
We consider the new divisor 179 and the new remainder 18,and apply the division lemma to get
179 = 18 x 9 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 770 and 573 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(179,18) = HCF(197,179) = HCF(573,197) = HCF(770,573) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1
Notice that 1 = HCF(18,1) .
