HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 972, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 972, 19 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 558, 972, 19 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 558, 972, 19 is 1.
HCF(558, 972, 19) = 1
HCF of 558, 972, 19 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 972, 19 is 1.
Highest Common Factor of 558,972,19 is 1
Step 1: Since 972 > 558, we apply the division lemma to 972 and 558, to get
972 = 558 x 1 + 414
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 414 and 558, to get
558 = 414 x 1 + 144
Step 3: We consider the new divisor 414 and the new remainder 144, and apply the division lemma to get
414 = 144 x 2 + 126
We consider the new divisor 144 and the new remainder 126,and apply the division lemma to get
144 = 126 x 1 + 18
We consider the new divisor 126 and the new remainder 18,and apply the division lemma to get
126 = 18 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 558 and 972 is 18
Notice that 18 = HCF(126,18) = HCF(144,126) = HCF(414,144) = HCF(558,414) = HCF(972,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 19 > 18, we apply the division lemma to 19 and 18, to get
19 = 18 x 1 + 1
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 1 and 18, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 18 and 19 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) .
