Given numbers are 402, 837, 509, 505
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 837) = 112158
GCD(402, 837) = ( 402 x 837 ) / 112158
= 402 / 837
= 402
Step2:
LCM(3, 509) = 1527
GCD(3, 509) = ( 3 x 509 ) / 1527
= 3 / 509
= 3
Step3:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
So, Greatest Common Divisor of 402, 837, 509, 505 is 1
