Given numbers are 340, 646, 402, 997
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 646) = 6460
GCD(340, 646) = ( 340 x 646 ) / 6460
= 340 / 646
= 340
Step2:
LCM(34, 402) = 6834
GCD(34, 402) = ( 34 x 402 ) / 6834
= 34 / 402
= 34
Step3:
LCM(2, 997) = 1994
GCD(2, 997) = ( 2 x 997 ) / 1994
= 2 / 997
= 2
So, Greatest Common Divisor of 340, 646, 402, 997 is 1
