Let's first find the prime factorization of 147,000....

147,000 = (147)(1,000)
= (3)(49)(1,000)
= (3)(7)(7)(1,000)
= (3)(7)(7)(10)(10)(10)
= (3)(7)(7)(2)(5)(2)(5)(2)(5)

Since there is only one unique way to write 147,000 as the product of prime numbers, we know that:
- three beads worth 2 points each were removed (i.e., three blue beads were removed)
- one bead worth 3 points each were removed (i.e., one green bead was removed)
- three beads worth 5 points each were removed (i.e., three yellow beads were removed)
- two beads worth 7 points each were removed (i.e., two red beads were removed)
