Given numbers are 470, 218, 402, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 218) = 51230
GCD(470, 218) = ( 470 x 218 ) / 51230
= 470 / 218
= 470
Step2:
LCM(2, 402) = 402
GCD(2, 402) = ( 2 x 402 ) / 402
= 2 / 402
= 2
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 470, 218, 402, 620 is 2
