Given numbers are 402, 788, 371, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 788) = 158388
GCD(402, 788) = ( 402 x 788 ) / 158388
= 402 / 788
= 402
Step2:
LCM(2, 371) = 742
GCD(2, 371) = ( 2 x 371 ) / 742
= 2 / 371
= 2
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 402, 788, 371, 520 is 1
