HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 572, 649, 889, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 572, 649, 889, 57 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 572, 649, 889, 57 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 572, 649, 889, 57 is 1.
HCF(572, 649, 889, 57) = 1
HCF of 572, 649, 889, 57 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 572, 649, 889, 57 is 1.
Highest Common Factor of 572,649,889,57 is 1
Step 1: Since 649 > 572, we apply the division lemma to 649 and 572, to get
649 = 572 x 1 + 77
Step 2: Since the reminder 572 ≠ 0, we apply division lemma to 77 and 572, to get
572 = 77 x 7 + 33
Step 3: We consider the new divisor 77 and the new remainder 33, and apply the division lemma to get
77 = 33 x 2 + 11
We consider the new divisor 33 and the new remainder 11, and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 572 and 649 is 11
Notice that 11 = HCF(33,11) = HCF(77,33) = HCF(572,77) = HCF(649,572) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 11, we apply the division lemma to 889 and 11, to get
889 = 11 x 80 + 9
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 9 and 11, to get
11 = 9 x 1 + 2
Step 3: We consider the new divisor 9 and the new remainder 2, and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 889 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(889,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1
Notice that 1 = HCF(57,1) .
