HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 710, 564 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 710, 564 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 621, 710, 564 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 621, 710, 564 is 1.
HCF(621, 710, 564) = 1
HCF of 621, 710, 564 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 710, 564 is 1.
Highest Common Factor of 621,710,564 is 1
Step 1: Since 710 > 621, we apply the division lemma to 710 and 621, to get
710 = 621 x 1 + 89
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 89 and 621, to get
621 = 89 x 6 + 87
Step 3: We consider the new divisor 89 and the new remainder 87, and apply the division lemma to get
89 = 87 x 1 + 2
We consider the new divisor 87 and the new remainder 2,and apply the division lemma to get
87 = 2 x 43 + 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 621 and 710 is 1
Notice that 1 = HCF(2,1) = HCF(87,2) = HCF(89,87) = HCF(621,89) = HCF(710,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 564 > 1, we apply the division lemma to 564 and 1, to get
564 = 1 x 564 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 564 is 1
Notice that 1 = HCF(564,1) .
