Given numbers are 438, 219, 163, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 219) = 438
GCD(438, 219) = ( 438 x 219 ) / 438
= 438 / 219
= 438
Step2:
LCM(219, 163) = 35697
GCD(219, 163) = ( 219 x 163 ) / 35697
= 219 / 163
= 219
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 438, 219, 163, 402 is 1
