Given numbers are 345, 655, 253, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 655) = 45195
GCD(345, 655) = ( 345 x 655 ) / 45195
= 345 / 655
= 345
Step2:
LCM(5, 253) = 1265
GCD(5, 253) = ( 5 x 253 ) / 1265
= 5 / 253
= 5
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 345, 655, 253, 978 is 1
