Given numbers are 700, 647, 642, 455
The list of prime factors of all numbers are
Prime factors of 700 are 2 x 2 x 5 x 5 x 7
Prime factors of 647 are 647
Prime factors of 642 are 2 x 3 x 107
Prime factors of 455 are 5 x 7 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 700, 647, 642, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(700, 647) = 452900
GCD(700, 647) = ( 700 x 647 ) / 452900
= 700 / 647
= 700
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 700, 647, 642, 455 is 1
