HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 900, 654 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 394, 900, 654 is 2 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 394, 900, 654 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 394, 900, 654 is 2.
HCF(394, 900, 654) = 2
HCF of 394, 900, 654 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 394, 900, 654 is 2.
Highest Common Factor of 394,900,654 is 2
Step 1: Since 900 > 394, we apply the division lemma to 900 and 394, to get
900 = 394 x 2 + 112
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 112 and 394, to get
394 = 112 x 3 + 58
Step 3: We consider the new divisor 112 and the new remainder 58, and apply the division lemma to get
112 = 58 x 1 + 54
We consider the new divisor 58 and the new remainder 54,and apply the division lemma to get
58 = 54 x 1 + 4
We consider the new divisor 54 and the new remainder 4,and apply the division lemma to get
54 = 4 x 13 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 394 and 900 is 2
Notice that 2 = HCF(4,2) = HCF(54,4) = HCF(58,54) = HCF(112,58) = HCF(394,112) = HCF(900,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 2, we apply the division lemma to 654 and 2, to get
654 = 2 x 327 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 654 is 2
Notice that 2 = HCF(654,2) .
