HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 511, 505, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 511, 505, 845 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 654, 511, 505, 845 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 654, 511, 505, 845 is 1.
HCF(654, 511, 505, 845) = 1
HCF of 654, 511, 505, 845 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 511, 505, 845 is 1.
Highest Common Factor of 654,511,505,845 is 1
Step 1: Since 654 > 511, we apply the division lemma to 654 and 511, to get
654 = 511 x 1 + 143
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 143 and 511, to get
511 = 143 x 3 + 82
Step 3: We consider the new divisor 143 and the new remainder 82, and apply the division lemma to get
143 = 82 x 1 + 61
We consider the new divisor 82 and the new remainder 61,and apply the division lemma to get
82 = 61 x 1 + 21
We consider the new divisor 61 and the new remainder 21,and apply the division lemma to get
61 = 21 x 2 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 654 and 511 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(61,21) = HCF(82,61) = HCF(143,82) = HCF(511,143) = HCF(654,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 1, we apply the division lemma to 505 and 1, to get
505 = 1 x 505 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 505 is 1
Notice that 1 = HCF(505,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 845 > 1, we apply the division lemma to 845 and 1, to get
845 = 1 x 845 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 845 is 1
Notice that 1 = HCF(845,1) .
