HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 333, 642 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 333, 642 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 440, 333, 642 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 440, 333, 642 is 1.
HCF(440, 333, 642) = 1
HCF of 440, 333, 642 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 333, 642 is 1.
Highest Common Factor of 440,333,642 is 1
Step 1: Since 440 > 333, we apply the division lemma to 440 and 333, to get
440 = 333 x 1 + 107
Step 2: Since the reminder 333 ≠ 0, we apply division lemma to 107 and 333, to get
333 = 107 x 3 + 12
Step 3: We consider the new divisor 107 and the new remainder 12, and apply the division lemma to get
107 = 12 x 8 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 440 and 333 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(107,12) = HCF(333,107) = HCF(440,333) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 642 > 1, we apply the division lemma to 642 and 1, to get
642 = 1 x 642 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 642 is 1
Notice that 1 = HCF(642,1) .
