Given numbers are 662, 513, 38, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 513) = 339606
GCD(662, 513) = ( 662 x 513 ) / 339606
= 662 / 513
= 662
Step2:
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
= 1 / 38
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 662, 513, 38, 642 is 1
