GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 348) = 37236
GCD(428, 348) = ( 428 x 348 ) / 37236
= 428 / 348
= 428
Step2:
LCM(4, 618) = 1236
GCD(4, 618) = ( 4 x 618 ) / 1236
= 4 / 618
= 4
Step3:
LCM(2, 890) = 890
GCD(2, 890) = ( 2 x 890 ) / 890
= 2 / 890
= 2
So, Greatest Common Divisor of 428, 348, 618, 890 is 2
