Given numbers are 745, 455, 214, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(745, 455) = 67795
GCD(745, 455) = ( 745 x 455 ) / 67795
= 745 / 455
= 745
Step2:
LCM(5, 214) = 1070
GCD(5, 214) = ( 5 x 214 ) / 1070
= 5 / 214
= 5
Step3:
LCM(1, 284) = 284
GCD(1, 284) = ( 1 x 284 ) / 284
= 1 / 284
= 1
So, Greatest Common Divisor of 745, 455, 214, 284 is 1
