HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 572 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 572 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 722, 572 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 722, 572 is 2.
HCF(722, 572) = 2
HCF of 722, 572 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 572 is 2.
Highest Common Factor of 722,572 is 2
Step 1: Since 722 > 572, we apply the division lemma to 722 and 572, to get
722 = 572 x 1 + 150
Step 2: Since the reminder 572 ≠ 0, we apply division lemma to 150 and 572, to get
572 = 150 x 3 + 122
Step 3: We consider the new divisor 150 and the new remainder 122, and apply the division lemma to get
150 = 122 x 1 + 28
We consider the new divisor 122 and the new remainder 28,and apply the division lemma to get
122 = 28 x 4 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 722 and 572 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(122,28) = HCF(150,122) = HCF(572,150) = HCF(722,572) .
