HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 397, 779, 59 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 397, 779, 59 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 780, 397, 779, 59 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 780, 397, 779, 59 is 1.
HCF(780, 397, 779, 59) = 1
HCF of 780, 397, 779, 59 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 397, 779, 59 is 1.
Highest Common Factor of 780,397,779,59 is 1
Step 1: Since 780 > 397, we apply the division lemma to 780 and 397, to get
780 = 397 x 1 + 383
Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 383 and 397, to get
397 = 383 x 1 + 14
Step 3: We consider the new divisor 383 and the new remainder 14, and apply the division lemma to get
383 = 14 x 27 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 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 780 and 397 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(383,14) = HCF(397,383) = HCF(780,397) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 779 > 1, we apply the division lemma to 779 and 1, to get
779 = 1 x 779 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 779 is 1
Notice that 1 = HCF(779,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 1, we apply the division lemma to 59 and 1, to get
59 = 1 x 59 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 59 is 1
Notice that 1 = HCF(59,1) .
