Given numbers are 398, 662, 762, 747
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 662) = 131738
GCD(398, 662) = ( 398 x 662 ) / 131738
= 398 / 662
= 398
Step2:
LCM(2, 762) = 762
GCD(2, 762) = ( 2 x 762 ) / 762
= 2 / 762
= 2
Step3:
LCM(2, 747) = 1494
GCD(2, 747) = ( 2 x 747 ) / 1494
= 2 / 747
= 2
So, Greatest Common Divisor of 398, 662, 762, 747 is 1
