HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 728, 558 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 442, 728, 558 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 442, 728, 558 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 442, 728, 558 is 2.
HCF(442, 728, 558) = 2
HCF of 442, 728, 558 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 442, 728, 558 is 2.
Highest Common Factor of 442,728,558 is 2
Step 1: Since 728 > 442, we apply the division lemma to 728 and 442, to get
728 = 442 x 1 + 286
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 286 and 442, to get
442 = 286 x 1 + 156
Step 3: We consider the new divisor 286 and the new remainder 156, and apply the division lemma to get
286 = 156 x 1 + 130
We consider the new divisor 156 and the new remainder 130,and apply the division lemma to get
156 = 130 x 1 + 26
We consider the new divisor 130 and the new remainder 26,and apply the division lemma to get
130 = 26 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 442 and 728 is 26
Notice that 26 = HCF(130,26) = HCF(156,130) = HCF(286,156) = HCF(442,286) = HCF(728,442) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 558 > 26, we apply the division lemma to 558 and 26, to get
558 = 26 x 21 + 12
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 12 and 26, to get
26 = 12 x 2 + 2
Step 3: We consider the new divisor 12 and the new remainder 2, and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 26 and 558 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(558,26) .
