HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 938, 725, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 938, 725, 18 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 558, 938, 725, 18 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 558, 938, 725, 18 is 1.
HCF(558, 938, 725, 18) = 1
HCF of 558, 938, 725, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 938, 725, 18 is 1.
Highest Common Factor of 558,938,725,18 is 1
Step 1: Since 938 > 558, we apply the division lemma to 938 and 558, to get
938 = 558 x 1 + 380
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 380 and 558, to get
558 = 380 x 1 + 178
Step 3: We consider the new divisor 380 and the new remainder 178, and apply the division lemma to get
380 = 178 x 2 + 24
We consider the new divisor 178 and the new remainder 24,and apply the division lemma to get
178 = 24 x 7 + 10
We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get
24 = 10 x 2 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 558 and 938 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(178,24) = HCF(380,178) = HCF(558,380) = HCF(938,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 725 > 2, we apply the division lemma to 725 and 2, to get
725 = 2 x 362 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 725 is 1
Notice that 1 = HCF(2,1) = HCF(725,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, 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 1 and 18 is 1
Notice that 1 = HCF(18,1) .
