HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 573, 710, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 573, 710, 77 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 573, 710, 77 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 573, 710, 77 is 1.
HCF(573, 710, 77) = 1
HCF of 573, 710, 77 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 573, 710, 77 is 1.
Highest Common Factor of 573,710,77 is 1
Step 1: Since 710 > 573, we apply the division lemma to 710 and 573, to get
710 = 573 x 1 + 137
Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 137 and 573, to get
573 = 137 x 4 + 25
Step 3: We consider the new divisor 137 and the new remainder 25, and apply the division lemma to get
137 = 25 x 5 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 573 and 710 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(137,25) = HCF(573,137) = HCF(710,573) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1
Notice that 1 = HCF(77,1) .
