Given numbers are 642, 655, 648, 150
The list of prime factors of all numbers are
Prime factors of 642 are 2 x 3 x 107
Prime factors of 655 are 5 x 131
Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 150 are 2 x 3 x 5 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 642, 655, 648, 150
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 655) = 420510
GCD(642, 655) = ( 642 x 655 ) / 420510
= 642 / 655
= 642
Step2:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
Step3:
LCM(1, 150) = 150
GCD(1, 150) = ( 1 x 150 ) / 150
= 1 / 150
= 1
So, Greatest Common Divisor of 642, 655, 648, 150 is 1
