HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 356, 428 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 431, 356, 428 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 431, 356, 428 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 431, 356, 428 is 1.
HCF(431, 356, 428) = 1
HCF of 431, 356, 428 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 431, 356, 428 is 1.
Highest Common Factor of 431,356,428 is 1
Step 1: Since 431 > 356, we apply the division lemma to 431 and 356, to get
431 = 356 x 1 + 75
Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 75 and 356, to get
356 = 75 x 4 + 56
Step 3: We consider the new divisor 75 and the new remainder 56, and apply the division lemma to get
75 = 56 x 1 + 19
We consider the new divisor 56 and the new remainder 19,and apply the division lemma to get
56 = 19 x 2 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 431 and 356 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(56,19) = HCF(75,56) = HCF(356,75) = HCF(431,356) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 428 > 1, we apply the division lemma to 428 and 1, to get
428 = 1 x 428 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 428 is 1
Notice that 1 = HCF(428,1) .
