HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 645, 456, 24, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 645, 456, 24, 884 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 645, 456, 24, 884 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 645, 456, 24, 884 is 1.
HCF(645, 456, 24, 884) = 1
HCF of 645, 456, 24, 884 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 645, 456, 24, 884 is 1.
Highest Common Factor of 645,456,24,884 is 1
Step 1: Since 645 > 456, we apply the division lemma to 645 and 456, to get
645 = 456 x 1 + 189
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 189 and 456, to get
456 = 189 x 2 + 78
Step 3: We consider the new divisor 189 and the new remainder 78, and apply the division lemma to get
189 = 78 x 2 + 33
We consider the new divisor 78 and the new remainder 33,and apply the division lemma to get
78 = 33 x 2 + 12
We consider the new divisor 33 and the new remainder 12,and apply the division lemma to get
33 = 12 x 2 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 645 and 456 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(33,12) = HCF(78,33) = HCF(189,78) = HCF(456,189) = HCF(645,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 3, we apply the division lemma to 24 and 3, to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 24 is 3
Notice that 3 = HCF(24,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 884 > 3, we apply the division lemma to 884 and 3, to get
884 = 3 x 294 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 884 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(884,3) .
