HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 142, 753 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 142, 753 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 321, 142, 753 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 321, 142, 753 is 1.
HCF(321, 142, 753) = 1
HCF of 321, 142, 753 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 321, 142, 753 is 1.
Highest Common Factor of 321,142,753 is 1
Step 1: Since 321 > 142, we apply the division lemma to 321 and 142, to get
321 = 142 x 2 + 37
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 37 and 142, to get
142 = 37 x 3 + 31
Step 3: We consider the new divisor 37 and the new remainder 31, and apply the division lemma to get
37 = 31 x 1 + 6
We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get
31 = 6 x 5 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 321 and 142 is 1
Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(142,37) = HCF(321,142) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 753 > 1, we apply the division lemma to 753 and 1, to get
753 = 1 x 753 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 753 is 1
Notice that 1 = HCF(753,1) .
