Given numbers are 440, 390, 570, 863
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(440, 390) = 17160
GCD(440, 390) = ( 440 x 390 ) / 17160
= 440 / 390
= 440
Step2:
LCM(10, 570) = 570
GCD(10, 570) = ( 10 x 570 ) / 570
= 10 / 570
= 10
Step3:
LCM(10, 863) = 8630
GCD(10, 863) = ( 10 x 863 ) / 8630
= 10 / 863
= 10
So, Greatest Common Divisor of 440, 390, 570, 863 is 1
