HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 368, 989, 239, 42 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 368, 989, 239, 42 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 368, 989, 239, 42 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 368, 989, 239, 42 is 1.
HCF(368, 989, 239, 42) = 1
HCF of 368, 989, 239, 42 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 368, 989, 239, 42 is 1.
Highest Common Factor of 368,989,239,42 is 1
Step 1: Since 989 > 368, we apply the division lemma to 989 and 368, to get
989 = 368 x 2 + 253
Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 253 and 368, to get
368 = 253 x 1 + 115
Step 3: We consider the new divisor 253 and the new remainder 115, and apply the division lemma to get
253 = 115 x 2 + 23
We consider the new divisor 115 and the new remainder 23, and apply the division lemma to get
115 = 23 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 368 and 989 is 23
Notice that 23 = HCF(115,23) = HCF(253,115) = HCF(368,253) = HCF(989,368) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 239 > 23, we apply the division lemma to 239 and 23, to get
239 = 23 x 10 + 9
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 9 and 23, to get
23 = 9 x 2 + 5
Step 3: We consider the new divisor 9 and the new remainder 5, and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 23 and 239 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(239,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
