Given numbers are 215, 624, 687, 564
The list of prime factors of all numbers are
Prime factors of 215 are 5 x 43
Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13
Prime factors of 687 are 3 x 229
Prime factors of 564 are 2 x 2 x 3 x 47
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 215, 624, 687, 564
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 624) = 134160
GCD(215, 624) = ( 215 x 624 ) / 134160
= 215 / 624
= 215
Step2:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
Step3:
LCM(1, 564) = 564
GCD(1, 564) = ( 1 x 564 ) / 564
= 1 / 564
= 1
So, Greatest Common Divisor of 215, 624, 687, 564 is 1
