GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 427) = 29890
GCD(490, 427) = ( 490 x 427 ) / 29890
= 490 / 427
= 490
Step2:
LCM(7, 891) = 6237
GCD(7, 891) = ( 7 x 891 ) / 6237
= 7 / 891
= 7
Step3:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
So, Greatest Common Divisor of 490, 427, 891, 165 is 1
