Given numbers are 280, 836, 399, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 836) = 58520
GCD(280, 836) = ( 280 x 836 ) / 58520
= 280 / 836
= 280
Step2:
LCM(4, 399) = 1596
GCD(4, 399) = ( 4 x 399 ) / 1596
= 4 / 399
= 4
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 280, 836, 399, 147 is 1
