Given numbers are 312, 662, 475, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 662) = 103272
GCD(312, 662) = ( 312 x 662 ) / 103272
= 312 / 662
= 312
Step2:
LCM(2, 475) = 950
GCD(2, 475) = ( 2 x 475 ) / 950
= 2 / 475
= 2
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 312, 662, 475, 490 is 1
