HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 650, 352, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 650, 352, 643 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 650, 352, 643 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 650, 352, 643 is 1.
HCF(650, 352, 643) = 1
HCF of 650, 352, 643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 650, 352, 643 is 1.
Highest Common Factor of 650,352,643 is 1
Step 1: Since 650 > 352, we apply the division lemma to 650 and 352, to get
650 = 352 x 1 + 298
Step 2: Since the reminder 352 ≠ 0, we apply division lemma to 298 and 352, to get
352 = 298 x 1 + 54
Step 3: We consider the new divisor 298 and the new remainder 54, and apply the division lemma to get
298 = 54 x 5 + 28
We consider the new divisor 54 and the new remainder 28,and apply the division lemma to get
54 = 28 x 1 + 26
We consider the new divisor 28 and the new remainder 26,and apply the division lemma to get
28 = 26 x 1 + 2
We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get
26 = 2 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 650 and 352 is 2
Notice that 2 = HCF(26,2) = HCF(28,26) = HCF(54,28) = HCF(298,54) = HCF(352,298) = HCF(650,352) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 643 > 2, we apply the division lemma to 643 and 2, to get
643 = 2 x 321 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 643 is 1
Notice that 1 = HCF(2,1) = HCF(643,2) .
