Given numbers are 894, 390, 357, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(894, 390) = 58110
GCD(894, 390) = ( 894 x 390 ) / 58110
= 894 / 390
= 894
Step2:
LCM(6, 357) = 714
GCD(6, 357) = ( 6 x 357 ) / 714
= 6 / 357
= 6
Step3:
LCM(3, 145) = 435
GCD(3, 145) = ( 3 x 145 ) / 435
= 3 / 145
= 3
So, Greatest Common Divisor of 894, 390, 357, 145 is 1
