Answer:
Pair are
30 , 3150
90, 1050
150, 630
210 , 450
Step-by-step explanation:
Let the numbers be a and b
a = 30x and b=30y
HCF of a and b = 30
Product of numbers = LCM * HCF
30x * 30y = 30 * 3150
30xy = 3150
xy = 3150/30 = 105
1*105 or 3* 35 or 5 * 21 or 7 * 15
1) 105 = 1*105
30xy =30*1 , 30*105 = (30 , 3150)
2) 105 = 3 * 35
30xy = 30*3 , 30*35 = 90 , 1050
90 , 1050
3) 150 , 630
4) 210 , 450
