HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 848, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 848, 790 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 561, 848, 790 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 561, 848, 790 is 1.
HCF(561, 848, 790) = 1
HCF of 561, 848, 790 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 848, 790 is 1.
Highest Common Factor of 561,848,790 is 1
Step 1: Since 848 > 561, we apply the division lemma to 848 and 561, to get
848 = 561 x 1 + 287
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 287 and 561, to get
561 = 287 x 1 + 274
Step 3: We consider the new divisor 287 and the new remainder 274, and apply the division lemma to get
287 = 274 x 1 + 13
We consider the new divisor 274 and the new remainder 13,and apply the division lemma to get
274 = 13 x 21 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 561 and 848 is 1
Notice that 1 = HCF(13,1) = HCF(274,13) = HCF(287,274) = HCF(561,287) = HCF(848,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 790 > 1, we apply the division lemma to 790 and 1, to get
790 = 1 x 790 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 790 is 1
Notice that 1 = HCF(790,1) .
