HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 442, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 442, 279 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 790, 442, 279 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 790, 442, 279 is 1.
HCF(790, 442, 279) = 1
HCF of 790, 442, 279 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 442, 279 is 1.
Highest Common Factor of 790,442,279 is 1
Step 1: Since 790 > 442, we apply the division lemma to 790 and 442, to get
790 = 442 x 1 + 348
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 348 and 442, to get
442 = 348 x 1 + 94
Step 3: We consider the new divisor 348 and the new remainder 94, and apply the division lemma to get
348 = 94 x 3 + 66
We consider the new divisor 94 and the new remainder 66,and apply the division lemma to get
94 = 66 x 1 + 28
We consider the new divisor 66 and the new remainder 28,and apply the division lemma to get
66 = 28 x 2 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 790 and 442 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(66,28) = HCF(94,66) = HCF(348,94) = HCF(442,348) = HCF(790,442) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 2, we apply the division lemma to 279 and 2, to get
279 = 2 x 139 + 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 279 is 1
Notice that 1 = HCF(2,1) = HCF(279,2) .
