Given numbers are 402, 228, 763, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 228) = 15276
GCD(402, 228) = ( 402 x 228 ) / 15276
= 402 / 228
= 402
Step2:
LCM(6, 763) = 4578
GCD(6, 763) = ( 6 x 763 ) / 4578
= 6 / 763
= 6
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 402, 228, 763, 155 is 1
