Given numbers are 390, 357, 857, 533
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 357) = 46410
GCD(390, 357) = ( 390 x 357 ) / 46410
= 390 / 357
= 390
Step2:
LCM(3, 857) = 2571
GCD(3, 857) = ( 3 x 857 ) / 2571
= 3 / 857
= 3
Step3:
LCM(1, 533) = 533
GCD(1, 533) = ( 1 x 533 ) / 533
= 1 / 533
= 1
So, Greatest Common Divisor of 390, 357, 857, 533 is 1
