HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 726, 442, 942 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 726, 442, 942 is 2 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 726, 442, 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 726, 442, 942 is 2.
HCF(726, 442, 942) = 2
HCF of 726, 442, 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 726, 442, 942 is 2.
Highest Common Factor of 726,442,942 is 2
Step 1: Since 726 > 442, we apply the division lemma to 726 and 442, to get
726 = 442 x 1 + 284
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 284 and 442, to get
442 = 284 x 1 + 158
Step 3: We consider the new divisor 284 and the new remainder 158, and apply the division lemma to get
284 = 158 x 1 + 126
We consider the new divisor 158 and the new remainder 126,and apply the division lemma to get
158 = 126 x 1 + 32
We consider the new divisor 126 and the new remainder 32,and apply the division lemma to get
126 = 32 x 3 + 30
We consider the new divisor 32 and the new remainder 30,and apply the division lemma to get
32 = 30 x 1 + 2
We consider the new divisor 30 and the new remainder 2,and apply the division lemma to get
30 = 2 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 726 and 442 is 2
Notice that 2 = HCF(30,2) = HCF(32,30) = HCF(126,32) = HCF(158,126) = HCF(284,158) = HCF(442,284) = HCF(726,442) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 942 > 2, we apply the division lemma to 942 and 2, to get
942 = 2 x 471 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 942 is 2
Notice that 2 = HCF(942,2) .
