HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 248, 640, 561 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 248, 640, 561 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 248, 640, 561 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 248, 640, 561 is 1.
HCF(248, 640, 561) = 1
HCF of 248, 640, 561 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 248, 640, 561 is 1.
Highest Common Factor of 248,640,561 is 1
Step 1: Since 640 > 248, we apply the division lemma to 640 and 248, to get
640 = 248 x 2 + 144
Step 2: Since the reminder 248 ≠ 0, we apply division lemma to 144 and 248, to get
248 = 144 x 1 + 104
Step 3: We consider the new divisor 144 and the new remainder 104, and apply the division lemma to get
144 = 104 x 1 + 40
We consider the new divisor 104 and the new remainder 40,and apply the division lemma to get
104 = 40 x 2 + 24
We consider the new divisor 40 and the new remainder 24,and apply the division lemma to get
40 = 24 x 1 + 16
We consider the new divisor 24 and the new remainder 16,and apply the division lemma to get
24 = 16 x 1 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 248 and 640 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(104,40) = HCF(144,104) = HCF(248,144) = HCF(640,248) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 561 > 8, we apply the division lemma to 561 and 8, to get
561 = 8 x 70 + 1
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 1 and 8, to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 561 is 1
Notice that 1 = HCF(8,1) = HCF(561,8) .
