Given numbers are 645, 268, 901, 290
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 268) = 172860
GCD(645, 268) = ( 645 x 268 ) / 172860
= 645 / 268
= 645
Step2:
LCM(1, 901) = 901
GCD(1, 901) = ( 1 x 901 ) / 901
= 1 / 901
= 1
Step3:
LCM(1, 290) = 290
GCD(1, 290) = ( 1 x 290 ) / 290
= 1 / 290
= 1
So, Greatest Common Divisor of 645, 268, 901, 290 is 1
