Given numbers are 928, 740, 280, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(928, 740) = 171680
GCD(928, 740) = ( 928 x 740 ) / 171680
= 928 / 740
= 928
Step2:
LCM(4, 280) = 280
GCD(4, 280) = ( 4 x 280 ) / 280
= 4 / 280
= 4
Step3:
LCM(4, 645) = 2580
GCD(4, 645) = ( 4 x 645 ) / 2580
= 4 / 645
= 4
So, Greatest Common Divisor of 928, 740, 280, 645 is 1
