HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 892, 668 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 892, 668 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 621, 892, 668 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 621, 892, 668 is 1.
HCF(621, 892, 668) = 1
HCF of 621, 892, 668 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 892, 668 is 1.
Highest Common Factor of 621,892,668 is 1
Step 1: Since 892 > 621, we apply the division lemma to 892 and 621, to get
892 = 621 x 1 + 271
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 271 and 621, to get
621 = 271 x 2 + 79
Step 3: We consider the new divisor 271 and the new remainder 79, and apply the division lemma to get
271 = 79 x 3 + 34
We consider the new divisor 79 and the new remainder 34,and apply the division lemma to get
79 = 34 x 2 + 11
We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 621 and 892 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(79,34) = HCF(271,79) = HCF(621,271) = HCF(892,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 668 > 1, we apply the division lemma to 668 and 1, to get
668 = 1 x 668 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 668 is 1
Notice that 1 = HCF(668,1) .
