HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 706, 435, 942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 706, 435, 942 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 706, 435, 942 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 706, 435, 942 is 1.
HCF(706, 435, 942) = 1
HCF of 706, 435, 942 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 706, 435, 942 is 1.
Highest Common Factor of 706,435,942 is 1
Step 1: Since 706 > 435, we apply the division lemma to 706 and 435, to get
706 = 435 x 1 + 271
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 271 and 435, to get
435 = 271 x 1 + 164
Step 3: We consider the new divisor 271 and the new remainder 164, and apply the division lemma to get
271 = 164 x 1 + 107
We consider the new divisor 164 and the new remainder 107,and apply the division lemma to get
164 = 107 x 1 + 57
We consider the new divisor 107 and the new remainder 57,and apply the division lemma to get
107 = 57 x 1 + 50
We consider the new divisor 57 and the new remainder 50,and apply the division lemma to get
57 = 50 x 1 + 7
We consider the new divisor 50 and the new remainder 7,and apply the division lemma to get
50 = 7 x 7 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 706 and 435 is 1
Notice that 1 = HCF(7,1) = HCF(50,7) = HCF(57,50) = HCF(107,57) = HCF(164,107) = HCF(271,164) = HCF(435,271) = HCF(706,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 942 > 1, we apply the division lemma to 942 and 1, to get
942 = 1 x 942 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 942 is 1
Notice that 1 = HCF(942,1) .
