Given numbers are 280, 738, 885, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 738) = 103320
GCD(280, 738) = ( 280 x 738 ) / 103320
= 280 / 738
= 280
Step2:
LCM(2, 885) = 1770
GCD(2, 885) = ( 2 x 885 ) / 1770
= 2 / 885
= 2
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 280, 738, 885, 705 is 1
