Given numbers are 278, 118, 705, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 118) = 16402
GCD(278, 118) = ( 278 x 118 ) / 16402
= 278 / 118
= 278
Step2:
LCM(2, 705) = 1410
GCD(2, 705) = ( 2 x 705 ) / 1410
= 2 / 705
= 2
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 278, 118, 705, 563 is 1
