HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 912, 542 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 912, 542 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 715, 912, 542 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 715, 912, 542 is 1.
HCF(715, 912, 542) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 912, 542 is 1.
Step 1: Since 912 > 715, we apply the division lemma to 912 and 715, to get
912 = 715 x 1 + 197
Step 2: Since the reminder 715 ≠ 0, we apply division lemma to 197 and 715, to get
715 = 197 x 3 + 124
Step 3: We consider the new divisor 197 and the new remainder 124, and apply the division lemma to get
197 = 124 x 1 + 73
We consider the new divisor 124 and the new remainder 73,and apply the division lemma to get
124 = 73 x 1 + 51
We consider the new divisor 73 and the new remainder 51,and apply the division lemma to get
73 = 51 x 1 + 22
We consider the new divisor 51 and the new remainder 22,and apply the division lemma to get
51 = 22 x 2 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 715 and 912 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(51,22) = HCF(73,51) = HCF(124,73) = HCF(197,124) = HCF(715,197) = HCF(912,715) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 1, we apply the division lemma to 542 and 1, to get
542 = 1 x 542 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 542 is 1
Notice that 1 = HCF(542,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
