HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 789, 564 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 789, 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 451, 789, 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 451, 789, 564 is 1.
HCF(451, 789, 564) = 1
HCF of 451, 789, 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 451, 789, 564 is 1.
Highest Common Factor of 451,789,564 is 1
Step 1: Since 789 > 451, we apply the division lemma to 789 and 451, to get
789 = 451 x 1 + 338
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 338 and 451, to get
451 = 338 x 1 + 113
Step 3: We consider the new divisor 338 and the new remainder 113, and apply the division lemma to get
338 = 113 x 2 + 112
We consider the new divisor 113 and the new remainder 112,and apply the division lemma to get
113 = 112 x 1 + 1
We consider the new divisor 112 and the new remainder 1,and apply the division lemma to get
112 = 1 x 112 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 451 and 789 is 1
Notice that 1 = HCF(112,1) = HCF(113,112) = HCF(338,113) = HCF(451,338) = HCF(789,451) .
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) .
