Given numbers are 640, 375, 862, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 375) = 48000
GCD(640, 375) = ( 640 x 375 ) / 48000
= 640 / 375
= 640
Step2:
LCM(5, 862) = 4310
GCD(5, 862) = ( 5 x 862 ) / 4310
= 5 / 862
= 5
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 640, 375, 862, 306 is 1
