HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 435, 743, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 435, 743, 394 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 435, 743, 394 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 435, 743, 394 is 1.
HCF(435, 743, 394) = 1
HCF of 435, 743, 394 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 435, 743, 394 is 1.
Highest Common Factor of 435,743,394 is 1
Step 1: Since 743 > 435, we apply the division lemma to 743 and 435, to get
743 = 435 x 1 + 308
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 308 and 435, to get
435 = 308 x 1 + 127
Step 3: We consider the new divisor 308 and the new remainder 127, and apply the division lemma to get
308 = 127 x 2 + 54
We consider the new divisor 127 and the new remainder 54,and apply the division lemma to get
127 = 54 x 2 + 19
We consider the new divisor 54 and the new remainder 19,and apply the division lemma to get
54 = 19 x 2 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 435 and 743 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(54,19) = HCF(127,54) = HCF(308,127) = HCF(435,308) = HCF(743,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get
394 = 1 x 394 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1
Notice that 1 = HCF(394,1) .
