Given numbers are 642, 790, 911, 340
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 790) = 253590
GCD(642, 790) = ( 642 x 790 ) / 253590
= 642 / 790
= 642
Step2:
LCM(2, 911) = 1822
GCD(2, 911) = ( 2 x 911 ) / 1822
= 2 / 911
= 2
Step3:
LCM(1, 340) = 340
GCD(1, 340) = ( 1 x 340 ) / 340
= 1 / 340
= 1
So, Greatest Common Divisor of 642, 790, 911, 340 is 1
