HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 342, 573 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 747, 342, 573 is 3 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 747, 342, 573 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 747, 342, 573 is 3.
HCF(747, 342, 573) = 3
HCF of 747, 342, 573 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 747, 342, 573 is 3.
Highest Common Factor of 747,342,573 is 3
Step 1: Since 747 > 342, we apply the division lemma to 747 and 342, to get
747 = 342 x 2 + 63
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 63 and 342, to get
342 = 63 x 5 + 27
Step 3: We consider the new divisor 63 and the new remainder 27, and apply the division lemma to get
63 = 27 x 2 + 9
We consider the new divisor 27 and the new remainder 9, and apply the division lemma to get
27 = 9 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 747 and 342 is 9
Notice that 9 = HCF(27,9) = HCF(63,27) = HCF(342,63) = HCF(747,342) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 9, we apply the division lemma to 573 and 9, to get
573 = 9 x 63 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 573 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(573,9) .
