Given numbers are 105, 278, 804, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 278) = 29190
GCD(105, 278) = ( 105 x 278 ) / 29190
= 105 / 278
= 105
Step2:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 105, 278, 804, 639 is 1
