Given numbers are 402, 390, 717, 526
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 390) = 26130
GCD(402, 390) = ( 402 x 390 ) / 26130
= 402 / 390
= 402
Step2:
LCM(6, 717) = 1434
GCD(6, 717) = ( 6 x 717 ) / 1434
= 6 / 717
= 6
Step3:
LCM(3, 526) = 1578
GCD(3, 526) = ( 3 x 526 ) / 1578
= 3 / 526
= 3
So, Greatest Common Divisor of 402, 390, 717, 526 is 1
