HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 357, 791, 559 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 357, 791, 559 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 357, 791, 559 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 357, 791, 559 is 1.
HCF(357, 791, 559) = 1
HCF of 357, 791, 559 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 357, 791, 559 is 1.
Highest Common Factor of 357,791,559 is 1
Step 1: Since 791 > 357, we apply the division lemma to 791 and 357, to get
791 = 357 x 2 + 77
Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 77 and 357, to get
357 = 77 x 4 + 49
Step 3: We consider the new divisor 77 and the new remainder 49, and apply the division lemma to get
77 = 49 x 1 + 28
We consider the new divisor 49 and the new remainder 28,and apply the division lemma to get
49 = 28 x 1 + 21
We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get
28 = 21 x 1 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 357 and 791 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(49,28) = HCF(77,49) = HCF(357,77) = HCF(791,357) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 559 > 7, we apply the division lemma to 559 and 7, to get
559 = 7 x 79 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 559 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(559,7) .
