The Largest common divisor has to be imbedded in the smallest number, as well as the others.

Take the smallest number: 4.72 x 10-34

Divide by a sequence of integers starting at 1, then 2, 3 etc, one at a time, till the number obtained divides evenly into all numbers. In this case the second try, 4.72/2 = 2.36 is successful since 2.36 x 10-34 divides evenly into all.
