HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 644, 180 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 644, 180 is 4 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 456, 644, 180 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 456, 644, 180 is 4.
HCF(456, 644, 180) = 4
HCF of 456, 644, 180 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 644, 180 is 4.
Highest Common Factor of 456,644,180 is 4
Step 1: Since 644 > 456, we apply the division lemma to 644 and 456, to get
644 = 456 x 1 + 188
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 188 and 456, to get
456 = 188 x 2 + 80
Step 3: We consider the new divisor 188 and the new remainder 80, and apply the division lemma to get
188 = 80 x 2 + 28
We consider the new divisor 80 and the new remainder 28,and apply the division lemma to get
80 = 28 x 2 + 24
We consider the new divisor 28 and the new remainder 24,and apply the division lemma to get
28 = 24 x 1 + 4
We consider the new divisor 24 and the new remainder 4,and apply the division lemma to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 456 and 644 is 4
Notice that 4 = HCF(24,4) = HCF(28,24) = HCF(80,28) = HCF(188,80) = HCF(456,188) = HCF(644,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 180 > 4, we apply the division lemma to 180 and 4, to get
180 = 4 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 180 is 4
Notice that 4 = HCF(180,4) .
