Given numbers are 642, 748, 313, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 748) = 240108
GCD(642, 748) = ( 642 x 748 ) / 240108
= 642 / 748
= 642
Step2:
LCM(2, 313) = 626
GCD(2, 313) = ( 2 x 313 ) / 626
= 2 / 313
= 2
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 642, 748, 313, 193 is 1
