HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 535, 431, 325 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 642, 535, 431, 325 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 642, 535, 431, 325 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 642, 535, 431, 325 is 1.
HCF(642, 535, 431, 325) = 1
HCF of 642, 535, 431, 325 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 642, 535, 431, 325 is 1.
Highest Common Factor of 642,535,431,325 is 1
Step 1: Since 642 > 535, we apply the division lemma to 642 and 535, to get
642 = 535 x 1 + 107
Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 107 and 535, to get
535 = 107 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 107, the HCF of 642 and 535 is 107
Notice that 107 = HCF(535,107) = HCF(642,535) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 107, we apply the division lemma to 431 and 107, to get
431 = 107 x 4 + 3
Step 2: Since the reminder 107 ≠ 0, we apply division lemma to 3 and 107, to get
107 = 3 x 35 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
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 107 and 431 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(107,3) = HCF(431,107) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 325 > 1, we apply the division lemma to 325 and 1, to get
325 = 1 x 325 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 325 is 1
Notice that 1 = HCF(325,1) .
