GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 374) = 120054
GCD(642, 374) = ( 642 x 374 ) / 120054
= 642 / 374
= 642
Step2:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
Step3:
LCM(1, 848) = 848
GCD(1, 848) = ( 1 x 848 ) / 848
= 1 / 848
= 1
So, Greatest Common Divisor of 642, 374, 621, 848 is 1
